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 -8c - c = -7c + 4y - 7 for c in terms of y.
| -15y + 2 | |
| -5y + 7 | |
| y + 8 | |
| 2y - \(\frac{3}{7}\) |
