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 4b + 9b = 3b - 7z - 3 for b in terms of z.
| 6z - 1 | |
| -\(\frac{4}{11}\)z + \(\frac{7}{11}\) | |
| 2\(\frac{3}{4}\)z - 2\(\frac{1}{4}\) | |
| -16z - 3 |
