m - 12 = 20

For 8 = m / 4, you multiply 4 on both sides to cancel it out, leaving it to be 8 x 4 = m, or 32 = m.

substitute 32 for m in the equation m - 12, so 32 - 12, which equals 20.

Answer:

If 8 = m/4, then m-12 = 20

Step-by-step explanation:

To solve this, we will follow the steps below;

First, we will find the value of m

8 = m/4

To find the value of m, we will multiply 4 to both-side of the equation

8 × 4 = m/4 ×  4

At the right-hand side of the equation, 4 will cancel-out 4, leaving us with just m

32 = m

m = 32

Then m-12  = 32 -12 = 20

Therefore, if 8 = m/4, then m-12 = 20
