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 -7c + 6c = 9c + 6z + 2 for c in terms of z.
| z - \(\frac{3}{5}\) | |
| z - \(\frac{1}{8}\) | |
| z - 7 | |
| 6z + 2 |
