selesaikan persamaan bwrikut ini 1.) 3x - 11 = 5 - x 2.) ⅓x - 3 = 2 + x : 4 3.) 5 - 2x = 3 (x + 1) sama caranya juga yaaa pliaseee....bsk dikumpulkan

1) 3x+x = 5+11
4x = 16
x = 4

2)1/3x -3 = 2+ x. 1/4
-3-2 = 1/4x - 1/3x
-5 = (3x-4x)/12
-5 = -1/12x
-5 . -12 = x
-60 = x

3) 5-2x = 3(x+1)
5-3 = 5x
2 = 5x
x = 2/5
