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