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