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 -2b - 2b = -5b - 8x - 9 for b in terms of x.
| -2x - 3 | |
| -\(\frac{1}{5}\)x - \(\frac{1}{5}\) | |
| 1\(\frac{3}{8}\)x + \(\frac{3}{4}\) | |
| x + \(\frac{7}{8}\) |
