Grace weighed 167 pounds before she started her exercise.

Lost: 45 pounds

Weight after exercise: 122 pounds

X represents the weight before she started.

Loss = subtraction

Subtract the lost weight from original weight she started with.

Original - lost = weight after exercise weeks

x - 45 = 122

Add 45 on BOTH sides

x - 45 + 45 = 122 + 45

x = 167 pounds

Hope this helps!
