2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
x-6-x-4=10-x -10=10-x -20=-x x=20 check: 20-6-20-4=10-20 -10=-10√
5 x 4 = 20 4 x 5 = 20
4x+20
x = .4% * 20 x = .004 * 20 x = .08.
20 = 1 x 20, 2 x 10, 4 x 5, 5 x 4, 10 x 2, 20 x 1.
4 is 20 percent of 20. 20 percent is equal to .20, so .20 x 20 = 4
x/4 + 5 = -1 (4)x/4 +(4)5 = -1 x+20 = -1 -20 -20 x= -21 x= -21
4_4_4_4 = 20 4/4+4*4=20 4/4 =1+4=5*4=20
If 20% = 4 We know that 20% x 5 = 100% So 4 x 5 = 20 So 4 is 20% of 20.
1 x 20, 2 x 10, 4 x 5, 5 x 4, 10 x 2, 20 x 1 = 20
The greatest common factor of -4 and -20 is -4.-4 x 1 = -4-4 x 5 = -20
