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 - 9b = 7b + 2x + 8 for b in terms of x.
| 3x - 1 | |
| -1\(\frac{2}{9}\)x - \(\frac{8}{9}\) | |
| x - \(\frac{3}{5}\) | |
| 6x + 7 |
