Question

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

Answer 1

A. 2/3x + 4/3 +3/4x + 3 = 2 17/12x + 13/3 = 2 17/12x= 2-13/3 17/12x=-7/3 x = -7/3 / 17/12 X = -84/51 b. X + 1/4x -3x = -1/2 -7/4x=-1/2 x= -1/2 / -7/4 = 4/14 maaf klo krang lengkap

Answer 2

Nomor 1 :
2/3(x+2) + 3/4(x+3) = 22x + 1/4x = 3x - 1/2
2/3x + 4/3 + 3/4x + 9/4 = 88/4x + 1/4x = 3x-1/2
2/3x + 3/4x + 4/3 + 9/4 = 89/4x = 3x - 1/2
8/12x + 9/12x + 16/12 + 27/4 =89/4x - 3x = -1/2
17/12x + 43/12 = 89/4x - 12/4x = -1/2
17/12x + 43/12 = 77/4x = -1/2
17/12x - 77/4x = -43/12 + 1/2
17/12x - 231/12x = -43/12 + 6/12
-214/12x = -37/12
12 (-214/12x) = (-37/12) 12
-214x = -37
x = -37/214 atau x = -0.17

nomor 2 :
x + 1/4x =3x -1/2
x + 1/4x - 3x = 1/2
4/4x + 1/4x - 12/4x = 1/2
-7/4x = 2/4
4 (-7/4x) = (2/4) 4
-7x = 2
x = 2/7 atau x = 0,28
