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
