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