-20=-4x-6x
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
4x = 20 so you have to divide both sides with 4, so that makes 4x : 4 = x 20 : 4 = 5 x = 5
4x =20x=20/4x=5
-20=-4x-6x
2x+4x=20 fiirst add the 2x and the 4x then u get 6x=20 Now you divide the six by both sides to cancel out the multiplacation on the left /6 /6 x=20 /6 now we simplifly the 20 over 6 to 10 /3 so x is 10 over 3
4x = 20 x = 5 (divide both sides by 4)
x/5 x 4/4 = 4x/20 3/4 x 5/5 = 15/20 (4x - 15)/20
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20
Yes, it does.
4x-20 in full work = -16
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
4x+2y = 20 2y = -4x+20 y = -2x+10
-20 = -4x +6 add 20 to both sides 0 = -4x +26 4x = 26 x = 26/4 = 6.5
4x - 3 = 17 4x = 17 + 3 4x = 20 x = 20 / 4 x = 5
-20 = -4x - 6x-20 = -10x20 = 10x2 = x
