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 -2c + 2c = -c + 6y - 8 for c in terms of y.
| -4y + 8 | |
| \(\frac{1}{9}\)y + \(\frac{7}{9}\) | |
| \(\frac{3}{16}\)y + \(\frac{1}{8}\) | |
| y + 9 |
