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 - 5a = 8a + 7x + 4 for a in terms of x.
| -\(\frac{12}{17}\)x - \(\frac{4}{17}\) | |
| -x - 1\(\frac{1}{2}\) | |
| -x - 4 | |
| \(\frac{3}{14}\)x - \(\frac{1}{2}\) |
