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 + 9a = 2a - 2y - 6 for a in terms of y.
| 1\(\frac{3}{8}\)y + \(\frac{3}{4}\) | |
| y - \(\frac{5}{16}\) | |
| 2y - \(\frac{1}{4}\) | |
| -\(\frac{9}{13}\)y - \(\frac{4}{13}\) |
