Question

when 7 times a number is decreased by 13, the answer is the same as 5 times the number is increased by 5. what was the number?

Answer 1

58
7(x) - 13 = 5(x) + 5
7x - 91 = 5x + 25
7x - 5x - 91 = 25
2x - 91 = 25
2x = 25 + 91
2x = 116
x = 58

Answer 2

I got 9.

Step - By - Step Explanation:

7x - 13 = 5x + 5

7x = 5x + 18

2x = 18

x = 18 ÷ 2 = 9

x = 9
