Let the first number equal x and the second number equal y. You have: A) x + y = 89. B) 4x + y = 155. First you rearrange equation A to obtain equation C) y = 89 - x Then substitute C) into B) to obtain equation D) 4x + 89 - x = 155 Solve equation D) for x to obtain x = 22. Place the value of x in equation C) to obtain y = 67. Thus your answer is {x = 22, y = 67}.
352.83 = (3 x 100) + (5 x 10) + (2 x 1) + (8/10) + (3/100)
89 = 8 x 8 x 8 x 8 x 8 x 8 x 8 x 8 x 8 = 134,217,728.
x + (x+1) + (x + 2) = 267 3x + 3 = 267 3x = 264 x = 88 Answer: 88, 89, 90
