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 - 2a = -8a + y + 4 for a in terms of y.
| -1\(\frac{3}{4}\)y + 1\(\frac{1}{4}\) | |
| 2\(\frac{4}{5}\)y - 1 | |
| 2\(\frac{1}{2}\)y - 1 | |
| \(\frac{3}{13}\)y + \(\frac{4}{13}\) |
