$24$ $24$

Isolate the variable $m$ $m$ by doing the same operation to both sides of the equation.

$- 12 = \frac{m}{8} - 15$ $-12=m/8-15$

$- 12 + 15 = \frac{m}{8} - 15 + 15$ $-12color(blue)(+15)=m/8-15color(blue)(+15)$

$3 = \frac{m}{8}$ $3=m/8$

$3 \cdot 8 = \frac{m}{8} \cdot 8$ $3color(blue)(*8)=m/8color(blue)(*8)$

$m = 24$ $m=24$

$m = 24$ $m=24$

Add $15$ $15$ to both sides:

$- 12 + 15 = \frac{m}{8} - 15 + 15$ $-12color(red)(+15)=m/8-15color(red)(+15)$

$3 = \frac{m}{8} + 0$ $3=m/8+0$

$3 = \frac{m}{8}$ $3=m/8$

Multiply both sides by $8$ $8$ :

$8 \times 3 = \frac{m}{8} \times 8$ $color(red)(8times)3=m/8color(red)(times8$

$24 = m$ $24=m$

$- 12 + 15 = \frac{m}{8}$ $-12 +15 = m/8$

$3 = \frac{m}{8}$ $3 = m/8$

Clear Denominator so Multiply the whole Equation by: $8$ $8$

$24 = m$ $24 = m$

How do you solve −12=m8−15-12= \frac { m } { 8} - 15?
