Best ResponseYou've already chosen the best response.0x+2y=8 x+2(6)=8 x+12=8 subtract 12 from both sides x=4 then divide by 1 both sides. since negative x x=4

Best ResponseYou've already chosen the best response.0x+2y=16 (i x+2y=8 (ii x+2y=16 x+2y=8 [+x and x cancelled] then , 4y=24 [adding 2y and 2y ; and 16+8] or y=24/4 therefore, y=6 Again keeping value of y in equation i, we get, x+2y=16 or x+2*6=16 or x +12=16 or x=1612 therefore, x=4
