Sum of two number = 95
Let the first number be x, then another number be x + 15 .
According to the question, x+x+15=95
=> 2x + 15 = 95
=> 2x + 15 - 15 = 95 - 15 [Subtracting 15 from both sides]
=> 2x=80
=> 2x/2=80/2 [Dividing both sides by 2]
=> x = 40
Hence, the first number = 40
And another number = 40 + 15=55
