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 + 6a = 8a + 4y + 5 for a in terms of y.
| \(\frac{1}{8}\)y - \(\frac{5}{16}\) | |
| \(\frac{9}{17}\)y + \(\frac{7}{17}\) | |
| -\(\frac{2}{5}\)y + \(\frac{3}{5}\) | |
| 17y + 9 |
