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 = 4a + 5x + 8 for a in terms of x.
| 1\(\frac{1}{7}\)x - \(\frac{1}{7}\) | |
| 1\(\frac{2}{3}\)x + \(\frac{2}{9}\) | |
| -1\(\frac{1}{2}\)x - 1\(\frac{1}{3}\) | |
| 1\(\frac{3}{8}\)x - \(\frac{3}{8}\) |
