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 -4a - 8a = -3a - 5x - 3 for a in terms of x.
| -3x + 3 | |
| -12x + 4 | |
| \(\frac{12}{13}\)x + \(\frac{7}{13}\) | |
| -\(\frac{1}{3}\)x + \(\frac{3}{5}\) |
