Best ResponseYou've already chosen the best response.1for substitution you need to solve one of the equation for x `or` y but 2nd equation is already solved for y then just plug that into the first equation

Best ResponseYou've already chosen the best response.1then now we plug it into y=8x13 y=8(2)13 y=3
