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