Answer 1

kararaljanabi77, this is the solution:

Let x to represent the smaller number

Let 4x + 9 represent the larger number

Therefore, the equation to solve for x is:

x + 4x + 9 = 69

Like terms:

5x = 69 - 9

5x = 60

Dividing by 5 at both sides:

5x/5 = 60/5

x = 12

The smaller number is 12, now let's find the larger number:

4x + 9

4 * 12 + 9

48 + 9

57

The larger number is 57
