Question 248527
you have 

(1)x+5y=8 and 
(2)x+y=4

you can use elimination:

Multiple equation (2) by -1

so now you have:

(1) x+5y=8
(2) -x-y=-4

add the equations and now you have

4y=4  divide both sides by 4

y=1

You now know y so sub into original equation (1)
x + 5(1) = 8
x+5=8  subtract 5 from both sides
x=3

your answer is (3,1)
