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 = 6a + 3x - 4 for a in terms of x.
| 7x - 9 | |
| -\(\frac{1}{13}\)x - \(\frac{7}{13}\) | |
| -4x + 2 | |
| -\(\frac{5}{8}\)x + \(\frac{7}{8}\) |
