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 8a + 2a = 3a - y - 6 for a in terms of y.
| -\(\frac{4}{5}\)y + \(\frac{1}{15}\) | |
| \(\frac{1}{2}\)y - \(\frac{2}{3}\) | |
| -\(\frac{1}{7}\)y - 1 | |
| -\(\frac{3}{5}\)y - 1\(\frac{1}{5}\) |
