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 - 6a = -7a - 6y + 4 for a in terms of y.
| y + \(\frac{1}{3}\) | |
| 3\(\frac{2}{5}\)y - \(\frac{4}{5}\) | |
| -1\(\frac{9}{10}\)y - \(\frac{3}{10}\) | |
| 2\(\frac{5}{6}\)y - \(\frac{1}{2}\) |
