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 -7a - 3a = 9a - y - 5 for a in terms of y.
| -2\(\frac{3}{4}\)y - \(\frac{1}{4}\) | |
| 3\(\frac{2}{3}\)y + 2 | |
| \(\frac{1}{2}\)y + \(\frac{1}{4}\) | |
| -\(\frac{1}{8}\)y + \(\frac{5}{16}\) |
