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 - 5a = 7a - x + 4 for a in terms of x.
| -6\(\frac{1}{2}\)x + 3 | |
| \(\frac{1}{9}\)x + \(\frac{4}{9}\) | |
| -1\(\frac{1}{3}\)x - 1\(\frac{1}{3}\) | |
| -3\(\frac{1}{2}\)x + \(\frac{1}{4}\) |
