Answer 1

Step-by-step explanation:

x represents the weight of Grace before she started the exercise program. Loss means subtraction, therefore, We will subtract the lost weight from original weight. Grace weighed 167 pounds before she started her exercise program

Answer 2

Answer

Grace weighed 167 pounds before she started her exercise program.

Step-by-step explanation:

Given,

Weight lost by Grace = 45 pounds

Weight of Grace after exercise weeks = 122 pounds

Let,

x represents the weight of Grace before she started the exercise program.

Loss means subtraction, therefore,

We will subtract the lost weight from original weight.

Original weight - Weight lost = Weight after exercise weeks

x-45=122

Adding 45 on both sides

\begin{gathered}x-45+45=122+45\\x=167\ pounds\end{gathered}

Grace weighed 167 pounds before she started her exercise program.
