Question

Tentukan nilai x
1. 2x + 4 = 0
2. 6x + 5 = 1
3. 2(x+4) = 0
4. 4x - 5 = x+4
5. 1/2 (10x - 12) = 0

tolong bantuannya ya, dan mohon ajarin caranya

Answer 1

1. 2x+4 =0
   2x     = 0-4
   2x     = -4
    x      = -4/2 = -2
2. 6x+5 = 1
   6x = 1-5
   6x= -4
    x = -4/6
    x = -2/3
3. 2 (x+4) =0
   2x+8 =0
   2x = 0-8
   2x = -8
    x = -8/2
    x= -4
4. 4x-5 = x+4
   4x-x = 4+5
    3x  = 9
     x= 9/3
     x= 3
5.1/2 (10x-12) =0
   5x -6 =0
   5x   = 0+6
   5x= 6
   x= 6/5 

maaf klo slah

Answer 2

1) 2x+4=0 (=) 2x=-4 (=) x=-2
2) 6x+5=1 (=) 6x=-4 (=) x=-2/3
3) 2(x+4)=0 (=) 2x+8=0 (=) 2x=-8 (=) x=-4
4) 4x-5=x+4 (=) 4x-x=4+5 (=) 3x=9 (=) x=3
5) 1/2(10x-12)=0 (=) 5x-6=0 (=) 5x=6 (=) x=6/5
