Question

Five times a number decreased by nine is equal to twice the number increased by 23. Which equation could be usedto solve the problem?5x - 9 = x + 235x - 9 = 2x + 235x + 23 + 2x = 235x + 23 = 2x + 23

Answer 1

Five times a number is written in math as = 5 x

decreased by nine means that we subtract 9 from the previous:

5 x - 9

equal to (use the equal sign "="

twice the number is: 2 x

increased by 29 menas to add 29 to the previous:

2 x + 29

The entire expression is:

5 x - 9 = 2 x + 29
