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 9a - 9a = 3a - 4x + 1 for a in terms of x.
| x - \(\frac{8}{13}\) | |
| \(\frac{5}{6}\)x + \(\frac{1}{6}\) | |
| 1\(\frac{1}{2}\)x + \(\frac{1}{8}\) | |
| -\(\frac{1}{3}\)x + \(\frac{5}{6}\) |
