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 - 4a = 8a - 2y + 3 for a in terms of y.
| \(\frac{3}{13}\)y - \(\frac{2}{13}\) | |
| -4y - 2\(\frac{1}{2}\) | |
| 3y - 2 | |
| -\(\frac{1}{8}\)y - \(\frac{3}{16}\) |
