solve using elimination method: 2x – y = 8, y = 5x + 3
do I change 2nd equation to : 5x -y =3? I am confused
so yes you are right and after this for we can eliminet the term of y so for we need multiply first equation by -1 and after this you assum thses two equations
2x-y=8 5x-y=-3
sorry 5x-y=-3 will be correct
so, how do I eliminate for the 'y' variable? do I multiply the reciprocal of one 'y' variable to one equation? Like for the 1st equation I would multiply '1' to eliminate the 'y'?
oh wait...I meant '-1' instead of 1
so 2x-y=8 5x-y=-3 multiply by -1 2x-y=8 -5x+y=3 ----------- -3x 0 =11 3x= - 11 x= -11/3
ok ?
and now calcule the y
then I get -2x + y = -8, then I add or subtract to 5x - y = -3? ---oh ok tyty
and now you can calcule the y yes ?
camon i will wait it
so if right ok than thank you the medal good luck bye
so if right ok than thank you the medal good luck bye
so y= 5x+3 y=5(-11/3) +3 =-55/3 +3 = (-55+9)/3 = -46/3
ok ?
yes thank you!
ok medal please
are you helping out people just to get a medal? that's a little wrong. you should help others out in the spirit of helpfulness, not greed!
no just for medal but just than the exersice will be signed solved right sure
