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