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 7a - 8a = 6a - 4y - 3 for a in terms of y.
| \(\frac{10}{13}\)y - \(\frac{2}{13}\) | |
| -\(\frac{8}{13}\)y - \(\frac{9}{13}\) | |
| -\(\frac{9}{14}\)y + \(\frac{4}{7}\) | |
| 4y - 3 |
