Question

Gente preciso da resposta cm resolusao Resolva a equasao A-2x=16 B-10-4x=x C-10-4x=x D-4x-6=28 E-5.(3-2x)=55 F-2x + 24=8x + 96

Answer 1

a)

2x = 16 
x = 16/2
x = 8
***************
b)

10 - 4x = x 
10 = x + 4x
10 = 5x
5x = 10
x = 10/5
x = 2
**************
c)

10 - 4x = x 
10 = x + 4x
10 = 5x
5x = 10
x = 10/5
x = 2
*******************
d)

4x - 6 = 28 
4x = 28 + 6
4x = 34 

x = 34  (:2)        17
      -----        =  -----
       4   (:2)         2

*****************************
e)
5.(3 - 2x) = 55 
15 - 10x = 55
15 - 55 = 10x
- 40 = 10x
10x = - 40
x = -40/10
x = - 4
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
f)
2x + 24 = 8x + 96
24 - 96 = 8x - 2x
- 72 = 6x
6x = - 72
x = - 72/6
x = - 12

Answer 2

A) 2x=16
     x=16/2
     x=8

B)10-4x=x
   -x -4x = -10
-5x=10
-x=10/5 (-1)
x=2

C) Igual a B

D)4x-6=28
4x=28+6
4x=34
x=34/4
x=17/2
  
E)5x(3-2x)=55
15x-10x = 55
5x= 55
x= 55/5
x= 11

F)2x+24=8x+96
2x-8x= 96-24
10x= 72
x=72/10 
x= 36/5

Espero ter ajudado :)
