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 -3a + 4a = a - 5y - 6 for a in terms of y.
| y + \(\frac{4}{7}\) | |
| \(\frac{1}{12}\)y + \(\frac{5}{12}\) | |
| 2\(\frac{1}{4}\)y + 1\(\frac{1}{2}\) | |
| 3\(\frac{1}{2}\)y - 2 |
