solve the equation

8.7=3.5m-2.5 (5.4-6m)

Simplifying

8.7 = 3.5m + - 2.5 (5.4 + - 6m)

8.7 = 3.5m + (5.4 * - 2.5 + - 6m * - 2.5)

8.7 = 3.5m + (-13.5 + 15m)

Reorder the terms:

8.7 = - 13.5 + 3.5m + 15m

Combine like terms: 3.5m + 15m = 18.5m

8.7 = - 13.5 + 18.5m

Solving

8.7 = - 13.5 + 18.5m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-18.5m' to each side of the equation.

8.7 + - 18.5m = - 13.5 + 18.5m + - 18.5m

Combine like terms: 18.5m + - 18.5m = 0.0

8.7 + - 18.5m = - 13.5 + 0.0

8.7 + - 18.5m = - 13.5

Add '-8.7' to each side of the equation.

8.7 + - 8.7 + - 18.5m = - 13.5 + - 8.7

Combine like terms: 8.7 + - 8.7 = 0.0

0.0 + - 18.5m = - 13.5 + - 8.7

-18.5m = - 13.5 + - 8.7

Combine like terms: - 13.5 + - 8.7 = - 22.2

-18.5m = - 22.2

Divide each side by '-18.5'.

m = 1.2

Simplifying

m = 1.2
