Question

Selesaikan persamaan linear berikut!

a. 2 - 2/3 x = 4

b. 3/4 (x + 3) + 1/2 (x-1=0)

c. 2x-3/3 + 4x+4/2 = 2x + 3




jawab yang bener yaa, aku kasih poin banyak tuh!

Answer 1

A. 2 - 2/3 x = 4
    - 2/3 x = 4-2
     -2/3 x = 2
     - x = 2 / 2/3
     - x = 2 * 3/2
     - x = 3
       x = -3

b. 3/4 (x + 3) + 1/2 (x-1) =0
    ---------------------------------------- * 4
3 ( x + 3) + 2 (x - 1) = 0
3x + 9 + 2x -2 = 0
5x = -7
x = - 7/5

c. 2x-3 /3 + 4x+4 /2 = 2x +3
 ---------------------------------------------- * 6
4x - 6 + 12 x + 12 = 12x + 18
16x -12 x = 18- 6
4x = 12
x = 3

begitu jawabannya, semoga membantu ^_^
