solve for x

= − 1 /2 :)

Step-by-step explanation:

Divide both sides of the equation by the same term

2 = − 1 2 2 = − 1 2

Simplify

Cancel terms that are in both the numerator and denominator

2 2 = − 1 2  

22x​=2−1​ = − 1 2  

x=2−1​ = − 1 2

Solution

= − 1 /2 :)

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
