Answer
m=2.4
Work Step by Step
Simplifying
2(5m + -6) + -13 = -1
Reorder the terms:
2(-6 + 5m) + -13 = -1
(-6 * 2 + 5m * 2) + -13 = -1
(-12 + 10m) + -13 = -1
Reorder the terms:
-12 + -13 + 10m = -1
Combine like terms: -12 + -13 = -25
-25 + 10m = -1
Solving
-25 + 10m = -1
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '25' to each side of the equation.
-25 + 25 + 10m = -1 + 25
Combine like terms: -25 + 25 = 0
0 + 10m = -1 + 25
10m = -1 + 25
Combine like terms: -1 + 25 = 24
10m = 24
Divide each side by '10'.
m = 2.4
Simplifying
m = 2.4
