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 - 6x - 3 for a in terms of x.
| x - 2 | |
| -\(\frac{6}{7}\)x - \(\frac{1}{14}\) | |
| -\(\frac{1}{2}\)x + 1\(\frac{1}{2}\) | |
| \(\frac{11}{13}\)x + \(\frac{3}{13}\) |
