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 - 7a = -9a + 2x - 1 for a in terms of x.
| \(\frac{1}{6}\)x + \(\frac{5}{6}\) | |
| \(\frac{9}{11}\)x - \(\frac{1}{11}\) | |
| -\(\frac{3}{7}\)x - 1 | |
| 2\(\frac{1}{2}\)x - 2\(\frac{1}{4}\) |
