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 - 3a = -9a - y + 7 for a in terms of y.
| -\(\frac{11}{15}\)y - \(\frac{4}{15}\) | |
| -\(\frac{12}{17}\)y + \(\frac{9}{17}\) | |
| \(\frac{2}{17}\)y + \(\frac{7}{17}\) | |
| -\(\frac{3}{4}\)y + 1 |
