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 a - 8a = -8a - 9y + 1 for a in terms of y.
| -\(\frac{2}{3}\)y + 2\(\frac{1}{3}\) | |
| -y + \(\frac{5}{13}\) | |
| -\(\frac{1}{9}\)y + \(\frac{1}{9}\) | |
| -\(\frac{5}{6}\)y + \(\frac{2}{3}\) |
