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 -3a - 4a = -4a - 9x - 2 for a in terms of x.
| -9x - 3 | |
| -5x - 2 | |
| \(\frac{3}{11}\)x - \(\frac{8}{11}\) | |
| \(\frac{3}{5}\)x + \(\frac{4}{5}\) |
