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 -9a - 8a = -3a + 7x + 2 for a in terms of x.
| -2\(\frac{1}{2}\)x - \(\frac{1}{3}\) | |
| -\(\frac{4}{7}\)x - 1\(\frac{1}{7}\) | |
| -3\(\frac{1}{2}\)x - 1 | |
| \(\frac{1}{14}\)x + \(\frac{9}{14}\) |
