Answer:
Step-by-step explanation:
Let the number = x
10 times a number = 10x
Twenty three more than 10 times a number : 10x + 23
10x + 23 = x + 5 {subtract x from both sides}
10x - x + 23 = x + 5 - x
9x + 23 = 5 {Subtract 23 from both sides}
9x = 5 - 23
9x = -18 {Divide both sides by 9}
9x/9 = -18/9
x = -2
The number = -2
