Question

Please help me with this.

Answer 1

12 = 12 + (v - 8)/2
Subtract 12 from both sides
0 = (v - 8)/2
Multiple both sides by 2
0 = v - 8
Add 8 to both sides
8 = v
Therefore A is correct

Answer 2

v=8

Explanation:

12=12+v−8/2

12=12+1/2

v+−4(Distribute)

12=(1/2v)+(12+−4)(Combine Like Terms)

12=1/2v+8

Step 2: Flip the equation.

1/2v+8=12

Step 3: Subtract 8 from both sides.

1/2v+8−8=12−8

Step 4: Multiply both sides by 2.

2*(1/2v)=(2)*(4)

v=8
