- 2X - 2 = 4 ?
If so.....,
- 2X - 2 = 4
add 2 to each side
- 2X = 6
divide each sides integers by - 2
X = - 3
==========check
- 2(- 3) - 2 = 4
6 - 2 = 4
4 = 4
-------------checks
-2x - 2 = 4-2x = 4 + 2-2x = 6x = 6/-2x = -3Check:-2(-3) - 2 = 46 - 2 = 44 = 4
2x + 4 = 2 2x = -2 x = -1
Divide both sides by two. x = 2 2x=4 2x/2=4/2 2x/2=1x=x 4/2=2 x=2
-2x - 10 + 4 = 2 -2x - 6 = 2 -2x = 2 + 6 -2x = 8 -x = 8 / 2 x = -4 Check: -2(-4) - 10 + 4 = 2 8 - 10 + 4 = 2 8 - 6 = 2 2 = 2
4+2x=9 -4 -4 2x=9 2x/2 9/2 x=4 1/2
-2x - 2 = 4-2x = 4 + 2-2x = 6x = 6/-2x = -3Check:-2(-3) - 2 = 46 - 2 = 44 = 4
2x + 4 = 2 2x = -2 x = -1
Divide both sides by two. x = 2 2x=4 2x/2=4/2 2x/2=1x=x 4/2=2 x=2
-2x - 10 + 4 = 2 -2x - 6 = 2 -2x = 2 + 6 -2x = 8 -x = 8 / 2 x = -4 Check: -2(-4) - 10 + 4 = 2 8 - 10 + 4 = 2 8 - 6 = 2 2 = 2
2x + 4 = 2(x + 2)
2x+4=30 (1.) Subtract 4 from both side 2x+4=30 -4 -4 2x =26 (2.) Divide 2 from 2x and 30 (2x/2, 26/2) x =13
2x * 2x (2*2=4) therefore, 2x*2x equals 4x2.
2 (2x) = 4x
(x2+3x-4) (x-4)
Here is how you solve this problem... 5x*4-3x*5*2x-9= (Combine like-terms) 5x-3x*2x= 2x*2x=(2x)2 (Add the rest of the problem) (2x)2*4*5-9=(2x)2*20-9 (2x)2*11 (2x)2 *11= your answer
2X divided by 4= 2X
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
