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 - 4a = -a - 8x - 4 for a in terms of x.
| -\(\frac{1}{2}\)x + 1\(\frac{3}{4}\) | |
| -\(\frac{4}{5}\)x - \(\frac{4}{5}\) | |
| \(\frac{1}{13}\)x - \(\frac{1}{13}\) | |
| \(\frac{6}{7}\)x + \(\frac{4}{7}\) |
