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 -4a + 2a = -9a - 8y - 3 for a in terms of y.
| -2y + 7 | |
| -2y - \(\frac{3}{5}\) | |
| -\(\frac{3}{5}\)y + \(\frac{1}{2}\) | |
| -\(\frac{2}{3}\)y + \(\frac{5}{6}\) |
