Question

Solve for m.
12.6+4m=9.6+8m12.6+4m=9.6+8m

Answer 1

3/4 =m

Explanation:

12.6+4m=9.6+8m

Subtract 4m from each side

12.6+4m-4m =9.6+8m-4m

12.6 = 9.6 +4m

Subtract 9.6 from each side

12.6 - 9.6 = 9.6 - 9.6 +4m

3 = 4m

Divide each side by 4

3/4 = 4m/4

3/4 =m

Answer 2

m = 3/4

Explanation:

12.6+4m=9.6+8m

Isolate the variable, m. Note the equal sign, what you do to one side, you do to the other.

Subtract 4m and 9.6 from both sides:

12.6 (-9.6) + 4m (-4m) = 9.6 (-9.6) + 8m (-4m)

12.6 - 9.6 = 8m - 4m

Simplify:

12.6 - 9.6 = 8m - 4m

3 = 4m

Isolate the variable, m. Divide 4 from both sides:

4m = 3

(4m)/4 = (3)/4

m = 3/4

3/4 is your answer for m.
