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