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 = -6a + 5x - 6 for a in terms of x.
| x - 2\(\frac{1}{2}\) | |
| -\(\frac{2}{13}\)x + \(\frac{9}{13}\) | |
| -4\(\frac{1}{3}\)x + 2 | |
| \(\frac{11}{12}\)x + \(\frac{1}{2}\) |
