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 9b + 6b = -9b + 7z - 5 for b in terms of z.
| \(\frac{1}{18}\)z - \(\frac{5}{18}\) | |
| -4\(\frac{1}{2}\)z + 3\(\frac{1}{2}\) | |
| 6z + 8 | |
| \(\frac{7}{11}\)z + \(\frac{4}{11}\) |
