diketahui persamaan 1/3(2x+1) = 1/4(3x-1). Nilai x + 2 adalaha. -7b. -5c. 7d. 9

1/3(2x + 1) = 1/4(3x -1)
2/3 x + 1/3 = 3/4 x - 1/4
2/3x - 3/4x = -1/4 - 1/3
8/12 x - 9/12 = -3/12 - 4/12
-1/12x = -7/12
-12x = 12. (-7)
-12x = -84
x = 7

x + 2 = 7 + 2 = 9 ---> D

1/3 (2x + 1) = 1/4 (3x - 1)
2/3x + 1/3 = 3/4x - 1/4
2/3x - 3/4x = -1/4 - 1/3
8/12x - 9/12x = -3/12 - 4/12
-1/12x = -7/12
x = -7/12 × -12/1
x = 7

Nilai x + 2
= 7 + 2
= 9  (D)
