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 7a - 9a = 4a + 3x - 3 for a in terms of x.
| -10x + 4 | |
| 2\(\frac{3}{5}\)x - \(\frac{4}{5}\) | |
| 4x - 1 | |
| x + \(\frac{3}{11}\) |
