Answer:

p = 72

q = 18

Step-by-step explanation:

Complementary means they add to  90o

p + q = 90

p = 4*q

Substitute 4q for p

4q + q = 90            Combine

5q = 90                  Divide by 5

5q/5 =90/5

q = 18

p = 4q

p = 4*18

p = 72

Answer:

6

Step-by-step explanation:

Let the two integers be a and b.

The difference of them is 26. Thus:

a-b=26

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

a=2+5b

Substitute:

a-b=26\\(2+5b)-b=26

Combine like terms:

4b+2=26

Subtract 2 from both sides:

4b=24

Divide by 4:

b=6

And the second number is:

a-b=26\\a-6=26

Add 6 to both sides:

a=32

So, our two numbers are 32 and 6

And the smaller integer is 6.

And we're done :)
