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 - 2a = -6a + 4x - 6 for a in terms of x.
| x + 1\(\frac{1}{6}\) | |
| \(\frac{1}{7}\)x + \(\frac{5}{7}\) | |
| 1\(\frac{1}{2}\)x - 1\(\frac{1}{2}\) | |
| -\(\frac{3}{10}\)x - \(\frac{1}{5}\) |
