nilai x yang memenuhi persamaan 1/2(x + 1) + 3x = 2/3 + 3x adalah....

1/2(x+1)+3x = 2/3+3x
1/2x+1/2 = 2/3+3x
1/2-2/3 = 3x+1/2x
-(1/6) = (7/2)x
x=-(1/6)*(2/7)
x= -(2/42)
x=[tex] \frac{1}{21} [/tex]

1/2 (x+1) + 3x = 2/3 + 3x
____________________ x 2

x + 1 + 6x = 2/6 + 6x
_________________ x 6

6x + 6 + 36x = 2 + 36 x
6x + 6 + 36x - 2 - 36x = 0
6x + 4 = 0
x = 4/6
x = 2/3

Semoga Membantu
