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