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 - 3a = -6a + 8y - 8 for a in terms of y.
| -5\(\frac{1}{2}\)y - 2 | |
| 2\(\frac{3}{4}\)y - 2 | |
| \(\frac{1}{13}\)y + \(\frac{3}{13}\) | |
| -2\(\frac{1}{2}\)y - 4 |
