Question

12.6+4m=9.6+8m
Solve for m

Answer 1

$12.6 + 4m = 9.6 + 8m \\ \: \: 4m - 8m = 9.6 - 12.6 \\ \: \: \: \: \: \: \: \: \: \: - 4m = - 3 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: 4m = 3 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: m = \frac{3}{4}$

Answer 2

12.6 + 4m = 9.6 + 8m

Subtracting 4m from both sides

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

12.6 = 9.6 + 4m

Subtracting 9.6 from both sides,

12.6 - 9.6 = 9.6 - 9.6 + 4m

3 = 4m

Divide both side by 4

3/4 = m
