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 - 4a = a + 2x - 5 for a in terms of x.
| -2x + 1\(\frac{2}{3}\) | |
| \(\frac{2}{3}\)x - \(\frac{1}{6}\) | |
| -\(\frac{3}{8}\)x - 1 | |
| -1\(\frac{2}{11}\)x - \(\frac{5}{11}\) |
