What is the solution of the system? x+8y=17 x+y=3

x + 8y = 17


x + y   = 
3


First subtract " x " with " x " ( which means subtract 8y
with " y " and 17 with 3 )


By subtracting, you should
et


7y = 14 now divide both
sides by 7


By dividing, you should
get


y = 2 which is your answer
for " y "


Now plug 2 into one of the
equatino


x + 2 = 3 subtract 2
on both sides


By subtracting, you should
get


x = 1 which is your answer
for " x " 


So your answer is x = 1 ; y =
2
