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 9a - 8a = -6a - 5y + 2 for a in terms of y.
| \(\frac{8}{13}\)y - \(\frac{4}{13}\) | |
| \(\frac{4}{5}\)y + 1\(\frac{1}{5}\) | |
| 4y - 2 | |
| \(\frac{1}{5}\)y + \(\frac{2}{15}\) |
