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 = 2a + 4y - 1 for a in terms of y.
| -1\(\frac{1}{2}\)y + 1\(\frac{1}{2}\) | |
| -\(\frac{2}{11}\)y - \(\frac{5}{11}\) | |
| 3\(\frac{1}{3}\)y - \(\frac{1}{3}\) | |
| 1\(\frac{1}{4}\)y - \(\frac{1}{8}\) |
