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