2.6 + 3.2r = -39
Solving
2.6 + 3.2r = -39
Solving for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '-2.6' to each side of the equation.
2.6 + -2.6 + 3.2r = -39 + -2.6
Combine like terms: 2.6 + -2.6 = 0.0
0.0 + 3.2r = -39 + -2.6
3.2r = -39 + -2.6
Combine like terms: -39 + -2.6 = -41.6
3.2r = -41.6
Divide each side by '3.2'.
r = -13
