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 - 8b = -3b + 9z + 6 for b in terms of z.
| 17z + 6 | |
| -\(\frac{7}{9}\)z - \(\frac{7}{9}\) | |
| 3z + 1\(\frac{2}{3}\) | |
| 2\(\frac{1}{2}\)z - 1 |
