Pertanyaan

persamaan linear
1. x-5 = 6x+10
2. x-2 = 3(4x-8)

Answer 1

1. x-5 = 6x+10
-5-10 = 6x - x
   -15 = 5 x
  - 3    = x

2. x-2 = 3(4x-8)
x-2   = 12x - 24
-2+24 = 12x - x
22 = 11x
2 = x

Answer 2

x-5 = 6x+10
x-6x = 10+5
-5x = 15
x = -3

x-2 = 3(4x-8)
x-2 = 12x-24
x-12x = -24+2
-11x = -22
x = 2
