Solve 15=5(1-m)-2(1-m)

$$15 = 5 ( 1 - m ) - 2 ( 1 - m )$$

Solve for m

$$m=-4$$

Steps for Solving Linear Equation

Use the distributive property to multiply 5 by 1-m.

$$15=5-5m-2\left(1-m\right)$$

Use the distributive property to multiply -2 by 1-m.

$$15=5-5m-2+2m$$

Subtract 2 from 5 to get 3.

$$15=3-5m+2m$$

Combine -5m and 2m to get -3m.

$$15=3-3m$$

Swap sides so that all variable terms are on the left hand side.

$$3-3m=15$$

Subtract 3 from both sides.

$$-3m=15-3$$

Subtract 3 from 15 to get 12.

$$-3m=12$$

Divide both sides by -3.

$$m=\frac{12}{-3}$$

Divide 12 by -3 to get -4.

$$m=-4$$
