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?

Step-by-step explanation:

Let the number be x

five times a number = 5x

Five times a number decreased by nine = 5x - 9

Twice the number increase by 23 = 2x + 23

5x - 9 = 2x + 23

5x - 2x = 23 + 9

3x = 32

x = 32/3

won't that be plagrisim thought?

step-by-step explanation:

x = 3 ± √(5+y)
