Finding the Unknown Class 7 Solutions with Step-by-Step Explanations

1. Multiple choice questions.

Q1. Which of the following is an equation?

(a) $3x + 5$
(b) $5y - 4$
(c) $4z = 20$
(d) Both (a) and (c)

Answer: (c) $4z = 20$

Q2. What is the solution of the equation $2n + 1 = 99$?

(a) $n=49$
(b) $n=50$
(c) $n=48$
(d) $n=51$

Answer: (a) $n=49$

Q3. If you divide both sides of an equation by the same non-zero number, the equation remains:

(a) True
(b) False
(c) Unchanged
(d) May or may not be true

Answer: (a) True

Q4. The process of finding the value of an unknown in an equation is called:

(a) Multiplying
(b) Adding
(c) Solving
(d) Dividing

Answer: (c) Solving

2. Very Short Answer (VSA).

Q1. What is an equation?

Answer: An equation is a mathematical statement showing the equality of two algebraic expressions using the ‘=’ sign.

Q2. What is the first step to solve $5x - 4 = 7$ systematically?

Answer: The first step is to add 4 to both sides of the equation to isolate the term with $x$.

Q3. Write the additive inverse of $-7$.

Answer: The additive inverse of $-7$ is $+7$.

Q4. If $2y = 14$, what is the value of $y$?

Answer: $y = 14 \div 2 = 7$.

Q5. What is meant by “solving an equation”?

Answer: Solving an equation means finding the value of the unknown for which both sides of the equation are equal.

3. Short Answer Questions.

Q1. Frame and solve an equation if the sum of a number and $8$ is $15$.

Answer: Let the number be $x$. The equation is $x + 8 = 15$. Subtract $8$ from both sides: $x = 15 - 8 = 7$. So, the required number is $7$.

Q2. Ramesh and Suresh together have $60$ marbles. Ramesh has $30$ more than Suresh. Find the number of marbles each has.

Answer: Let Suresh have $y$. Ramesh has $y + 30$. Their total: $y + (y+30) = 60 \Rightarrow 2y + 30 = 60 \Rightarrow 2y = 30 \Rightarrow y = 15$. Ramesh has $15 + 30 = 45$ and Suresh has $15$.

Q3. Jasmine creates a matchstick arrangement using exactly $99$ sticks with the rule $2n+1$ matchsticks at the $n^{th}$ position. What is $n$?

Answer: $2n+1=99 \Rightarrow 2n=98 \Rightarrow n=49$. So, position number $49$ uses $99$ sticks.

Q4. State the steps to solve the equation $6y + 7 = 4y + 21$.

Answer:

Subtract $4y$ from both sides: $6y + 7 - 4y = 21$
$2y + 7 = 21$
Subtract $7$: $2y = 14$
Divide by $2$: $y = 7$

Q5. Create an equation with the solution $x = -2$ and solve it.

Answer: Equation: $3x + 6 = 0$. Solving, $3x = -6 \Rightarrow x = -2$.

4. True or False Questions.

Q1. An equation remains the same if you add the same number to both sides.

Answer: True

Q2. $5x = 13$ has more than one solution for $x$.

Answer: False

Q3. The solution for $4k + 1 = 13$ is $k = 3$.

Answer: True

Q4. The equation $3y + 2 = 3y + 2$ has infinitely many solutions.

Answer: True

Q5. In the equation $a + b = c + d$, adding the same number to both $a$ and $c$ changes the equality.

Answer: False

3. Fill in the Blanks Questions.

Q1. To solve $u / 15 = 6$, $u$ equals __________.

Answer: $90$

Q2. The value of $k$ in $4k + 1 = 13$ is __________.

Answer: $3$

Q3. The equation $x + 7 = 12$ gives $x = $ __________.

Answer: $5$

Q4. If you subtract one sack from each plate, the balance is maintained because __________.

Answer: Equal weights are removed from both sides.

Q5. The process of finding a value for the unknown that satisfies an equation is called __________ the equation.

Answer: Solving
