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
[tex]x - 45 = 122[/tex]
Adding 45 on both sides
[tex]x - 45+ 45= 122+45[/tex]
[tex]x=167 pounds[/tex]
Grace weighed 167 pounds before she started her exercise program.
