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