Isilah jawaban ini dengan benar. sekian terimakasih

Answer 1

1. 2x-5/3=x-3
=>2x-5=3(x-3)
=>2x-5=3x-9
=>2x-3x=-9+5
=>-x=-4
=>x=4

6.4(2-y)<y+5
=>8-4y<y+5
=>-4y-y<5-8
=>-5y<-3
=>y>-3/-5
=>y>3/5

7.1-(x+9)<2x+7
=>1-x-9>2x+7
=>-x-8>2x+7
=>-x-2x>7+8
=>-3x>15
=>x<15/-3
=>x<-5

8.5(a-6)<2(3a+1)
=>5a-30<6a+2
=>5a-6a<2+30
=>-a<32
=>a>-32

9.2(x+1)-3(x-1)<_x+5
=>2x+2-3x+3<_x+5
=>-x+5<_x+5
=>-x-x<_5-5
=>-2x<_0
=>x>_0/-2=0

10.x-1/2<x+2/3
=>2(x+2)<3(x-1)
=>2x+4<3x-3
=>2x-3x<-3-4
=>-x<-7
=>x>7

maaf cuma itu....
