The sum of three integers is 8. The first integer is 9 times the second. The difference of the second and first is equal to the third.

Question

I have no idea how in the world to solve this question and really can not afford to fail another test can someone please help me

Answer 1

Lets break this down. Call the first integer x. Then the second integer is 9x. The third integer is the difference between the first two ( difference always means subtraction) so the third integer is x-9x=-8x

So our. Integers are x, 9x and -8x and thei sum is 8 so

x+9x -8x=8

2x=8. X=4 this is the first integer. 9x=36 which is our second integer -8x=-32 which is our third integer

So the three integers are 4,36 and -32. Do these add up to 8

Yes

There we go

Remember integers are whole numbers both positive and negative including zero. They are our counting numbers
