Question

How do you solve \[z-17.2=7.13\]?

Answer 1

Hint: In this problem, we have to solve the given equation and find the value of z. We can first add 17.2 on both the left-hand side and the right-hand side of the given equation. We can then simplify the right-hand side by adding it and simplify the left-hand side by cancelling the similar terms. We will then get the value of z.

Complete step by step solution:
We know that the given equation to be solved and find the value of z is,
 \[z-17.2=7.13\]
Now we can add 17.2 on both the left-hand side and the right-hand side of the given equation, we get
\[\Rightarrow z-17.2+17.2=7.13+17.2\]
We can now We can then simplify the right-hand side by adding it and simplify the left-hand side by cancelling the similar terms, we get
\[\Rightarrow z=24.33\]
Therefore, the value of z = 24.33 whose equation is \[z-17.2=7.13\].

Note: Students make mistakes while adding or subtracting correct numbers to the equation in order to cancel the number with z and to find the value of z. we should also concentrate while adding the decimal numbers and we should place the decimal point correctly. We can now check whether the answer is correct or not by substituting it in the given equation.
We can now substitute z = 24.33 in the given equation \[z-17.2=7.13\], we get
\[\begin{align}
  & \Rightarrow 24.33-17.2=7.13 \\
 & \Rightarrow 7.13=7.13 \\
\end{align}\]
Therefore, the value of z = 24.33 is a correct answer.
