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 -3a + 10a = -8a - 9y + 4 for a in terms of y.
| \(\frac{1}{2}\)y - 1 | |
| -\(\frac{11}{14}\)y - \(\frac{1}{7}\) | |
| -3\(\frac{4}{5}\)y + \(\frac{4}{5}\) | |
| 6y + 1\(\frac{1}{2}\) |
