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