The sum of two numbers is 156 one number is 28 more than the second number what are the numbers?
This problem can be solved by substituting (x) for the unknown number and (x + 28) as the number that is 28 more than the unknown number. Set up and solve the problem: x + (x + 28) = 156 (then simplify): 2x + 28 = 156 (subtract 28 from both sides of the equation to isolate the known numbers from the unknown): 2x = 128 (divide both sides by 2 to find the value of x) x (the unkown number) = 64 (now use the value of x to prove the answer) 64 + (64 + 28) = 64 + 92 = 156
