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