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 - 7y - 5 for a in terms of y.
| -\(\frac{1}{2}\)y - \(\frac{5}{8}\) | |
| -\(\frac{7}{12}\)y + \(\frac{1}{12}\) | |
| 1\(\frac{5}{8}\)y + \(\frac{1}{4}\) | |
| -\(\frac{2}{11}\)y + \(\frac{8}{11}\) |
