1)
(4-3x) =4
-3x =4-4
-3x =0
x=0
2)
2x +(3x-8)=4
2x +3x =8+4
5x =12
x=12/5
3)
2 x + ( 3 x - 8 ) = - 4
2x + 3x =-4+8
5x = 4
x= 4/5
4)
5 ( 2 x - 3 ) = 2 ( 3 - 5 x )
10x -30 = 6-10x
10x + 10x = 6+30
20x =36
x=36/20
x=18/10
x=9/5
5)
2 x + ( 8 - 3 × ) = ( × - 4)
2x + 8 -3x = x -4
2x -3x -x = -4 -8
-2x = -12
x =6
