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