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 + 3a = 8a - 2y + 5 for a in terms of y.
| -\(\frac{1}{2}\)y + 3 | |
| 1\(\frac{2}{5}\)y + \(\frac{9}{10}\) | |
| -1\(\frac{1}{4}\)y + \(\frac{1}{2}\) | |
| \(\frac{5}{13}\)y - \(\frac{5}{13}\) |
