okay you can solve this system of equations by two methods: elimination and substitution. Because y is given (in the second equation), substitution method would be the easiest.

anonymous · Answer

so plug in y=x-2 in place of y in the first equation.

anonymous · Answer

can you answer ?

anonymous · Answer

okay... 
so, 
8x+13(x-2) = 2
8x+13x-26=2
21x-26=2
21x=2+26
21x=28
x=28/21
x=4/3

alright :) thanks for helping i will give you medal ;)

anonymous · Answer

now that you have x, plug in x in either of the equations to find out y. since eq. 2 is easier, i would do 4/3 - 2 = -2/3 is your y.
