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