Question

me ajudem a responder algumas equaçoes :
5x+16-6=3x+7-10x
-11x+3x-6=22
2(x-1)-7=16
7(x-2)=5(x+3)
2(x-6)=-3(5+x)

Answer 1

5x+16-6=3x+7-10x
5x-3x+10x=7-16+6
12x=-3
x=-  3 
      12
x= -  1 
       4

-11x+3x-6=22
-11x+3x=22+6
-8x=28 .(-1)
8x=-28
x=-  28 
       8
x= -  14 
         4

2(x-1)-7=16
2x-2-7=16
2x=16+2+7
2x=25
x=  25 
       2

7(x-2)=5(x+3)
7x-14=5x+15
7x-5x=15+14
2x=29
x=  29 
       2

2(x-6)=-3(5+x)
2x-12=-15-3x
2x+3x=-15+12
5x=-3
x=-  3 
       5
