20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
20
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
20 + x = 55x = 55 -20x= 35
(20 * x) + 3 = 5 20 * x = 2 x = 1/10
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
20
4x =20x=20/4x=5
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
20 + x = 55x = 55 -20x= 35
7x=20+20x collect terms containg x on one side and then factorize -13x=20 0r, x=-20/13
It is the same as: 9+20x+20 = 20x+29
(20 * x) + 3 = 5 20 * x = 2 x = 1/10
280
The given terms can be simplified to: 20x+20
140/20=7
The GCF is 20.
