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 = -3c - y + 7 for c in terms of y.
| -\(\frac{1}{3}\)y + 3 | |
| 11y - 3 | |
| 3y + 2\(\frac{1}{2}\) | |
| -3y + 7 |
