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 - 9a = -4a - 8x - 5 for a in terms of x.
| \(\frac{1}{5}\)x - \(\frac{1}{5}\) | |
| -\(\frac{2}{7}\)x + \(\frac{1}{14}\) | |
| \(\frac{1}{2}\)x - 2\(\frac{1}{2}\) | |
| \(\frac{1}{7}\)x - 1\(\frac{1}{7}\) |
