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 = 9a - x + 3 for a in terms of x.
| \(\frac{6}{13}\)x - \(\frac{3}{13}\) | |
| 3x + \(\frac{2}{3}\) | |
| \(\frac{1}{2}\)x - 2 | |
| 2\(\frac{1}{7}\)x + \(\frac{4}{7}\) |
