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 = 8c + 9y + 5 for c in terms of y.
| -5y + 6 | |
| -4\(\frac{1}{2}\)y - 3 | |
| -\(\frac{7}{10}\)y - \(\frac{1}{2}\) | |
| \(\frac{12}{17}\)y + \(\frac{3}{17}\) |
