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