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 - 4a = -4a - 8x - 2 for a in terms of x.
| \(\frac{5}{13}\)x + \(\frac{5}{13}\) | |
| -\(\frac{3}{10}\)x - \(\frac{3}{10}\) | |
| -2\(\frac{1}{7}\)x - \(\frac{3}{7}\) | |
| \(\frac{4}{5}\)x + \(\frac{2}{5}\) |
