if 4x = 1/16then x = (1/16)/4so x = 1/64
4x24=96 20 x 4 = 80 4 x 4 = 16 80 + 16 = 96

4x - 7 = -15 4x = -8 x = -2
If: 4x = x+15 Then: x = 5
by 4. You do this because you want to find out what x equals. If you divide by 16, you find out what 1/4X equals, and that isn't much good to you. x=4 is the answer.
4x - 1 = 15 Therefore, 4x = 16 x = 16/4 Therefore, x = 4
2(4x)=16 8x=16 x=2 24x=16 x=16/24 x=2/3
4x + 3 = 16 Therefore, 4x = 13 x = 13/4 Therefore, x = 3.25
4x = 16Divide each side of the equation by 4:x = 4
4x+4y=16 y=5 4x+ 20=16 4x=-4 x=-1
-4x-4 equals -16. Add 4 to both sides; -4x equals -12. Divide both sides by -4; x equals 3.
8x + 9.16 = 4x + 16 8x - 4x = 16 - 9.16 4x = 6.84 x= 1.71
4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x
if 4x = 1/16then x = (1/16)/4so x = 1/64
4x - 9 = 7 4x = 16 x = 4
-4x - 7 = 16 -4x = 16 + 7 -4x = 23 x = -23/4 x = -5.75 Check: -4(-5.74) - 7 = 16 23 - 7 = 16 16 = 16
