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 + 6a = -9a - 3y - 6 for a in terms of y.
| -1\(\frac{1}{5}\)y + \(\frac{2}{5}\) | |
| -9y - 6 | |
| -1\(\frac{1}{2}\)y + 1\(\frac{1}{2}\) | |
| -11y - 6 |
