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 - 3a = 5a + 6x + 4 for a in terms of x.
| \(\frac{1}{12}\)x + \(\frac{1}{6}\) | |
| -1\(\frac{2}{7}\)x - \(\frac{4}{7}\) | |
| \(\frac{2}{9}\)x - 1 | |
| -1\(\frac{4}{13}\)x + \(\frac{2}{13}\) |
