Is x=2 a solution equation of 3(x-4)+8=x? How do you solve this?

Answer 1

well...

3(x-4)+8=x
3x - 12 + 8 = x
-4 = -2x
2 = x

...yes it is

Answer 2

Replace x with 2.
3(2-4) + 8 = 2
3(-2) + 8 = 2
-6 + 8 = 2
2 = 2
Yes, x=2 is a solution to this equation.

Answer 3

3(x-4)+8=x. 3x-12+8=x. 3x-x-4=x-x. 2x-12+8=0. 2x-4+4=0+4.
(2x=4)/2. X=2. Check: 3(x-4)+8=x. 3(2-4)+8=2. 3(-2)+8=2.
-6+8= 2. 2=2. x=2 is the correct solution of the problem.

Answer 4

Yes, it is 2...
IF we are going to substitute 2 to x, it would look like this:

3 (2-4) + 8 = 2
3 (-2) + 8 = 2
- 6 + 8 = 2
2 = 2

or

3 (-2) + 8 =2
-6 + 8 = 2
8 = 2 +6
8 = 8

LOL

since the results are equal, 2 is correct. haha.

Answer 5

3(x-4)+8=X
3(2-4)+8=2
3(-2)+8=2
-6+8=2
2=2
yes
substitute 2 for all instsances of x and solve

Answer 6

yes 2 is correct 3 (2-4)+8=2

3(-2) + 8
-6+8=2
2=2

Answer 7

Yes, its right.
To Solve:
1) 2-4 = -2
2) 3 x -2 = -6
3) -6 + 8 = 2

Answer 8

yes, multiply out 3(x-4) to get 3x - 12
then 3x - 12 + 8 = x (-12 + 8 = -4)
3x - 4 = x
move the x to the left hand side and the 4 to the right hand side. When doing so, change the sign of each number/letter
3x - x = 4
2x = 4
x = 4/2
x=2

Answer 9

yea its valid 3(2-4)+8=2 will turn out to be -6+8=2 which is 2=2

Answer 10

3[x-4]+8=x
3[2-4]+8=2
3[-2]+8 =2
-6+8=2

Answer 11

you substitute

3(2-4)+8=2
3(-4)+8=2
-12+8=2
-2=2
so then its not equal so draw a line through the equal sign and thats it
