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 6a + 5a = -a - 9x + 7 for a in terms of x.
| -2x + 1 | |
| 1\(\frac{8}{9}\)x - \(\frac{2}{3}\) | |
| -5x + 2\(\frac{1}{2}\) | |
| -\(\frac{3}{5}\)x - \(\frac{2}{5}\) |
