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 7a - a = 5a - 3y + 5 for a in terms of y.
| -\(\frac{1}{4}\)y - \(\frac{1}{2}\) | |
| -y + 2\(\frac{1}{2}\) | |
| y - \(\frac{3}{5}\) | |
| 1\(\frac{1}{2}\)y + \(\frac{3}{4}\) |
