5-6x+21=8-4x
-6x+4x=8-21-5
-2x= -18
x= -18/-2 (minus sign(-) will cancel)
x=9
ans= 9

5-3(2x-7)=8-4x
5-6x+21=8-4x
-6x+4x=8-5-21
-2x=-18
x= -18/-2=9

Hrm..
First, distribute the -3.
5 - 6x + 21 = 8 - 4x
Next, get all of the x's on one side, and the constants on the other.
-2x = -18
Finally, just divide by -2.
x = 9
All done! :)

1] 4(3x - 1) - (x - 2) = 42 ......... distribute => 12x - 4 - x + 2 = 42 ........... add like terms => 11x - 2 = 42 ..................... add 2 to both sides => 11x = 44 => x = 4 -------------- Do the rest the same way. ---------------- ¨
