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 -2a + 8a = -3a + 2y - 8 for a in terms of y.
| -\(\frac{8}{13}\)y - \(\frac{4}{13}\) | |
| -2\(\frac{1}{3}\)y - 1\(\frac{2}{3}\) | |
| 5y + 6 | |
| -6y - 8 |
