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 -2a - 4a = 5a - 2y - 3 for a in terms of y.
| -1\(\frac{4}{5}\)y - \(\frac{1}{5}\) | |
| -19y - 2 | |
| -\(\frac{2}{7}\)y + \(\frac{3}{7}\) | |
| -\(\frac{1}{12}\)y - \(\frac{1}{4}\) |
