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 -6c + 8c = -c + 9z - 2 for c in terms of z.
| -5z - 3 | |
| z + 4 | |
| -\(\frac{1}{5}\)z + \(\frac{2}{5}\) | |
| -4\(\frac{2}{3}\)z + 3 |
