Answer:
6
Step-by-step explanation:
Let the two integers be a and b.
The difference of them is 26. Thus:

One of them (let's use a) is 2 more than 5 times the other. Thus:

Substitute:

Combine like terms:

Subtract 2 from both sides:

Divide by 4:

And the second number is:

Add 6 to both sides:

So, our two numbers are 32 and 6
And the smaller integer is 6.
And we're done :)
5y-5y^2-5+2+2y+3y^2-1
collect like terms
7y-2y^2-4
reorder the terms
-2y^2+7y-4
-2y^2+7y-4 is your final answer, I hope this helps!
