Question

Rezolvati multimea ° ecuatiile:
A) 2(x+1)-7=9
B)16-(x-1)=7
C) (x-3):4+1=2
D)24:(2x-5)-2=6
VA ROG DAU COROANA+29 PUNCTE

Answer 1

2(x+1)=16/:2
x+1=8/-1
x=7
-(x-1)=-9
-x+1=-9/-1
-x=-10=>x=10
(x-3):4=1
x-3=4=>x=7
24:(2x-5)=8/×24
2x-5=192/+5
2x=197=>x=98,5

Answer 2

A) 2(x+1)-7=9 => 2(x+1)=9+7=16=>x+1=16:2=> x+1=8
x=8-1
x=7
B)16-(x-1)=7
x-1=7+16
x-1=23
x=23+1
x=24
C) (x-3):4+1=2
(x-3):4=2-1=1
x-3=1×4
x=4+3
x=7
D)24:(2x-5)-2=6
24:(2x-5)=6+2=8
2x-5=24:8
2x-5=3
2x=5+3
2x=8
x=8:2=4
Sper ca te am ajutat!!!
