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 = 6a - x - 5 for a in terms of x.
| -\(\frac{1}{2}\)x + \(\frac{5}{8}\) | |
| \(\frac{5}{17}\)x - \(\frac{4}{17}\) | |
| -\(\frac{1}{8}\)x + \(\frac{3}{4}\) | |
| -6x + 4 |
