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 + 8a = -3a - 2y + 8 for a in terms of y.
| 10y - 8 | |
| \(\frac{1}{2}\)y - \(\frac{3}{5}\) | |
| y - 2\(\frac{2}{3}\) | |
| \(\frac{1}{11}\)y + \(\frac{4}{11}\) |
