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 -3a - 6a = -4a - 4y + 2 for a in terms of y.
| -\(\frac{1}{2}\)y + \(\frac{3}{10}\) | |
| 2y + 2 | |
| -1\(\frac{1}{9}\)y - \(\frac{4}{9}\) | |
| 1\(\frac{7}{8}\)y + \(\frac{3}{8}\) |
