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 -3c - 6c = -4c + 8z - 4 for c in terms of z.
| -9z + 1 | |
| -1\(\frac{2}{3}\)z + 2\(\frac{1}{3}\) | |
| 14z - 4 | |
| 2z - 2 |
