1/2(2x-5)+2/3(6-x)=5/6x tolong jawab

jawab


1/2 (2x - 5) + 2/3 (6 - x) = 5/6 x.............kalikan 6
3(2x - 5) + 4(6 - x) = 5x
6x - 15 + 24 - 4x = 5x
2x + 9 = 5x
- 3x = - 9
x = 3

1/2 (2x - 5) + 2/3 (6 - x) = 5/6 x
x - 5/2 + 4 - 2/3 x = 5/6 x
1x - 2/3 x - 5/6 x = 5/2 - 4
6/6 x - 4/6 x - 5/6 x = 2,5 - 4
-3/6 x = -1,5
-0,5 x = -1,5
x = -1,5/-0,5
= 3

Semoga membantu:)
