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