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 + 4a = -5a + 4y - 6 for a in terms of y.
| 4\(\frac{1}{2}\)y - 1\(\frac{1}{2}\) | |
| y + 6 | |
| 11y - 6 | |
| -1\(\frac{1}{8}\)y - \(\frac{1}{2}\) |
