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