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