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