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 8c + 4c = 9c - 9z - 3 for c in terms of z.
| \(\frac{2}{3}\)z + 1 | |
| 13z + 3 | |
| -1\(\frac{2}{3}\)z - \(\frac{1}{2}\) | |
| 13z + 5 |
