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 + a = -8a + 7y - 5 for a in terms of y.
| \(\frac{3}{8}\)y - \(\frac{5}{16}\) | |
| -\(\frac{5}{11}\)y - \(\frac{8}{11}\) | |
| 1\(\frac{1}{2}\)y + 1\(\frac{3}{4}\) | |
| -\(\frac{1}{2}\)y + \(\frac{1}{2}\) |
