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 -7a - 2a = -2a + 6x - 6 for a in terms of x.
| -1\(\frac{3}{5}\)x + 1\(\frac{1}{5}\) | |
| 4x - \(\frac{1}{2}\) | |
| -2\(\frac{1}{2}\)x - 4 | |
| -\(\frac{1}{13}\)x + \(\frac{3}{13}\) |
