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