Chapter 2: Problem 7

Translate each statement into an equation and then solve the equation for the unknown number. 13 plus an unknown number is equal to 51.

Short Answer

Expert verified
Answer: The unknown number is 38.

Step by step solution

01

Translate the statement into an equation

The statement says "13 plus an unknown number is equal to 51." We can use the variable x to represent the unknown number. The equation should be: 13 + x = 51.
02

Solve for the unknown number x

To solve for x, we need to isolate x. We'll do this by subtracting 13 from both sides of the equation. This will give us: x = 51 - 13.
03

Find the value of x

Calculate the value of x by subtracting 13 from 51: x = 38. So, the unknown number is 38.
