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

-4x+2x=6x-24-2-3

(-1)-2x-6x=-29

8x=29

x=29/8

 

5x+2(x+6)-7x=3x+8

5x+2x+12-7x=3x+8

7x-7x-3x=8-12

(-1)-3x=-4

3x=4

x=4/3

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

-4X + 3 = - 2X + 6X - 24 - 2

3 + 24 + 2 = - 2X + 6X + 4X

29 = 8X


X = 29/8


5x + 2 ( x + 6 ) -7 x =3x+8

5X + 2X + 12 - 7X = 3X + 8

12 = 3X + 8

12 - 8 = 3X

4 = 3X

 

X = 4/3
