Answer:
Explanation:
2(6 + 4x) = 8x + 6
12 + 8x = 8x +6
12 -6 + 8x = 8x + 6 -6
6 + 8x = 8x
6 + 8x - 8x = 8x -8x
6 = 0
no solution
2(4x -2) = 10x -6
8x -4 = 10x -6
8x - 4 +4 = 10x -6 +4
8x = 10x - 2
8x - 10x = 10x -10x -2
-2x = -2
-2x/-2 = -2 /-2
x = 1
7 + x = 2x +6
7 -6 + x = 2x +6 -6
1 + x = 2x
1 + x -x = 2x -x
1 = x
2x + 2 = 2(1 - x)
2x + 2 = 2 - 2x
2x +2 -2 = 2 -2 - 2x
2x = -2x
2x + 2x = -2x + 2x
4x = 0
4x/4 = 0/4
x = 0
I could not get x = all real numbers for any of the equations.
I believe that these are the answers.
1. 2(6+4x)=8x+6 No Solution
2. 2(4x − 2) = 10x – 6 x=1
3. 7+x=2x+6 x=1
4. 2x+2=-2(1-x) No Solution
Hope this helps
