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 8a - 7a = 3a - 2y + 7 for a in terms of y.
| 1\(\frac{1}{7}\)y - \(\frac{1}{14}\) | |
| -\(\frac{1}{4}\)y + \(\frac{1}{2}\) | |
| y + 1\(\frac{2}{5}\) | |
| 3\(\frac{1}{3}\)y - \(\frac{2}{3}\) |
