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