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 5a - 8a = -8a - 2y + 5 for a in terms of y.
| \(\frac{6}{13}\)y + \(\frac{5}{13}\) | |
| 1\(\frac{2}{3}\)y - \(\frac{8}{9}\) | |
| -1\(\frac{2}{3}\)y + 1\(\frac{1}{3}\) | |
| -\(\frac{4}{9}\)y + \(\frac{1}{3}\) |
