Selesaikan persamaan linear berikut! a. 2-2/3x=4 b.3/4(x+3)+1/2(x-1=0) c.2x-3/3+4x+4/2=2x+3

A. 2 - 2/3x = 4 -2/3x = 4-2 x = 2 : -2/3 x = 2 x 3/-2 x= -3
b. 3/4x + 4 +1/2x - 1/2 = 0 5/4x = 1/2 - 4 x = -7/2 : 5/4 x = -14/5
c. x = 3/2
maaf ya kalau slah :)

Abiiahh
Dari jawaban yg sudah ada, aku koreksi ya untuk B dan C nya jawabanya ini :) B) 3/4(x+3)+1/2(x-1=0) 3/4x+9/4+1/2x-1/2=0 = 3/4x+1/2x+9/4-1/2=0 = 5/4x + 7/4 = 0 x = 5/4 x 4/7 x= 5/7
-2/3x = 4-2
x = 2 : -2/3
x = 2 x 3/-2
x= -3
b. 3/4x + 4 +1/2x - 1/2 = 0
5/4x = 1/2 - 4
x = -7/2 : 5/4
x = -14/5
c. x = 3/2
maaf ya kalau slah :)
B) 3/4(x+3)+1/2(x-1=0)
3/4x+9/4+1/2x-1/2=0
= 3/4x+1/2x+9/4-1/2=0
= 5/4x + 7/4 = 0
x = 5/4 x 4/7
x= 5/7
C) 2x-3/3+4x+4/2=2x+3
= 2x+4x-2x-1+2-3=0
= 4x-2 = 0
=4x= -2
x= -2/4 = -1/2
