To solve area, you must multiply length and width. In this case, we are simplifying an expression. The expression would be 4x + 1 x 2x - 3. We must combine like terms. 4x and 2x are like terms. 4x multiplied by 2x would be 8x. The problem is now 8x + 1 - 3. 1 and 3 are like terms. 1 - 3 would be negative 2 (-2). This means the "answer" is 8x + -2.
