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 - 7a = 9a - 2y - 3 for a in terms of y.
| 14y - 5 | |
| -\(\frac{2}{3}\)y + 3 | |
| 4\(\frac{1}{4}\)y + 1\(\frac{3}{4}\) | |
| -\(\frac{5}{17}\)y + \(\frac{3}{17}\) |
