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 4a + 5a = -6a + 3y - 1 for a in terms of y.
| 1\(\frac{2}{9}\)y - \(\frac{5}{9}\) | |
| -\(\frac{1}{5}\)y - \(\frac{1}{10}\) | |
| y + 2\(\frac{2}{3}\) | |
| \(\frac{7}{13}\)y + \(\frac{6}{13}\) |
