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 2a - 9a = 3a + 2y - 4 for a in terms of y.
| \(\frac{7}{16}\)y + \(\frac{7}{16}\) | |
| y + \(\frac{1}{6}\) | |
| -11y + 4 | |
| 1\(\frac{1}{5}\)y - \(\frac{1}{10}\) |
