Question

Ada yang tau?

perintahnya tentukan nilai x

yang bisa mohon bantuannya yah

Answer 1

1. 2(x-17) = 6
2x - 34 = 6
2x = 6 + 34
2x = 40
X = 40 : 2
X = 20

Answer 2

1)
2(x - 17) = 6
x - 17 = 6 : 2
x - 17 = 3
x = 3 + 17
x = 20

2)
4x(2) = 3(x + 4)
8x = 3x + 12
8x - 3x = 12
5x = 12
x = 12/5

3)
 (x - 2) 1/2 = 4x - 3
x - 2 = 2(4x - 3)
x - 2 = 8x - 6
x - 8x = -6 + 2
-7x = -4
  x = 4/7

4)
 (x - 3)/2 = 6x + 3
x - 3 = 2(6x + 3)
x - 3 = 12x + 6
x - 12x = 6 + 3
-11x = 9
  x = - 9/11

5)
4x - 3 = (3x - 4)/9
9(4x - 3) = 3x - 4
36x - 27 = 3x - 4
36x - 3x = -4 + 27
33x = 23
   x = 23 / 33
