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