When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -7b - 6b = -8b - 4x - 5 for b in terms of x.
| -12x - 2 | |
| -2\(\frac{1}{3}\)x - 1\(\frac{1}{3}\) | |
| 2x - 5 | |
| -5x + 4 |
