Question

Five times a number decreased by nine is equal to twice the number increased by 23. which equation could be used to solve the problem? 5x – 9 = x 23 5x – 9 = 2x 23 5x 23 2x = 23 5x 23 = 2x 23

Answer 1

Explanation:

5x-9 = 2(x+23) or 5x-9 = 2x+46

Let' x be the "number."

"Five times a number decreased by nine" means: 5x - 9

"equal to twice the number increased by 23" means: = 2(x+23)

Put them together: 5x-9 = 2(x+23)

5x-9 = 2(x+23)

5x-9 = 2x+46
