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 -9a + 2a = -4a - 3x + 6 for a in terms of x.
| x - 1\(\frac{1}{5}\) | |
| -\(\frac{3}{4}\)x + 2 | |
| -\(\frac{4}{7}\)x - \(\frac{4}{7}\) | |
| 5x + 6 |
