Question

hacer:
4x=28
2x-7=9
6x-5=-x+15
7x-11=6-10x
5(x-8)=0
2(x+4)=x1
3(2x-5)=2(15-x)-1


porfa si me pueden explicar agradeceria mucho!!

Answer 1

$4x= 28 =     x= \frac{28}{4} = 7$

$2x-7=9      2x= 9+7      x= \frac{16}{2} = 8$

Answer 2

Resolver.

Ecuaciones de 1°er grado.

4x = 28
 
  x = 28/4
 
  x = 7

...............................................................

2x - 7 = 9

2x = 9 + 7
 
2x = 16
 
  x = 16/2
 
  x = 8

................................................................

6x - 5 = - x + 15

6x + x = 15 + 5
 
   7x = 20 
 
     x = 20/7 

............................................................................

7x - 11 = 6 - 10x

7x + 10x = 6 + 11
 
     17x = 17
 
         x = 17/17 
 
          x = 1

......................................................................

5(x - 8) = 0

5x - 40 = 0

5x = 40 
 
  x = 40/5
 
  x = 8

.......................................................................

2(x + 4) = x

2x + 8 = x

2x - x = 8
  
  x = 8
