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 6a + a = -7a + 9y + 8 for a in terms of y.
| -1\(\frac{1}{4}\)y + 2 | |
| \(\frac{8}{13}\)y + \(\frac{8}{13}\) | |
| -\(\frac{5}{6}\)y - \(\frac{1}{2}\) | |
| -2y + 1\(\frac{4}{5}\) |
