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 + 6c = 8c - 7y - 3 for c in terms of y.
| 11y + 6 | |
| -1\(\frac{4}{5}\)y + 1\(\frac{1}{5}\) | |
| 1\(\frac{1}{12}\)y + \(\frac{1}{4}\) | |
| -7y - 9 |
