Answer:
the last choice
Step-by-step explanation:

To solve this one-step equation you:
1. Substract 9 in both sides of the equation:
In this step is the mistake as Sara gets as result -4x=29 and the corret result of substract 9 in both sides of the equation is 5x=20.
2. Divide both sides of the equation into 5:
Then, the answer that Sara should found for the equation is x=4

Answer:
y=-1/8y+1
Step-by-step explanation:
flip the equation, then add -8 to both sides to cancel out the +8 on the left, then divide sides by -8Let's solve for x.
y=−8x+8
Step 1: Flip the equation.
−8x+8=y
Step 2: Add -8 to both sides.
−8x+8+−8=y+−8
−8x=y−8
Step 3: Divide both sides by -8.
