Hello, Ayanna! Since you do not know the identity of the “number,” you can use a variable, such as x, to represent it. Also, since 19 is added to the number, you will now have an mathematical expression of x + 19. Next, the sum is 96. The word sum means the answer to an addition problem. Therefore, you must solve the equation x + 19 = 96. Solve for x to determine what is added to 19 to get a sum of 96.
