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