Answer: 28, 30, 32

Step-by-step explanation: The first integer is 28, the second is 30, and the third is 32. The difference from the first integer and the last integer should be 4. x is the first integer, so the equation is:

x+x+2+x+4=90

The first integer plus the second integer(x+2) plus the third integer(x+4) equals 90. Now solve.

x+x+2+x+4=90

3x+6=90

-6 -6

3x=84

/3 /3

x=28

So the first integer is 28, second is 30, third is 32.

Hope this helps!
