Question

Solve the following equation and check your result: $3x = 2x + 18$

Answer 1

Hint: The addition is the sum of given two or more than two numbers, or variables and in addition, if we sum the two or more numbers then we obtain a new frame of the number will be found, also in subtraction which is the minus of given two or more than two numbers, but here comes with the condition that in subtraction the greater number sign represented in the number will stay constant example $2 - 3 = - 1$

Complete step by step answer:
Since from given that the unknown variable is $x$ and we need to find that $x$ using the equation $3x = 2x + 18$
Now let us convert the given as variables in the left-hand side and the number on the right-hand side then we get $3x - 2x = 18$
By the subtraction operation, we get $x = 18$ where since $3 - 2 = 1$ so then the variable $3x - 2x = x(3 - 2) = x(1) = x$ where one into anything is the value that we input only.
Hence, we get the variable as $x = 18$ which is also the positive integer.

Note:
The other two operations are multiplication and division operations.
Since multiplicand refers to the number multiplied. Also, a multiplier refers to multiplying the first number. Have a look at an example; while multiplying $5 \times 7$ the number $5$ is called the multiplicand and the number $7$ is called the multiplier. Like $2 \times 3 = 6$ or which can be also expressed in the form of $2 + 2 + 2(3times)$
The process of the inverse of the multiplication method is called division. Like $x \times y = z$ is multiplication thus the division sees as $x = \dfrac{z}{y}$. Like $y = - \dfrac{{33}}{{11}} \Rightarrow - 3$
If the values are crossing into the equals to symbol then the sign of the values gets change like $3x = 2x \Rightarrow 3x - 2x = 0$
