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 + 8b = -4b + 4z + 2 for b in terms of z.
| \(\frac{1}{3}\)z + 1 | |
| \(\frac{1}{6}\)z - \(\frac{2}{3}\) | |
| -\(\frac{4}{11}\)z + \(\frac{2}{11}\) | |
| z - 9 |
