Answer 2

Por favor ajudem nessas equacoes2x-3+x=-5+2x 

2x - 3 + x = - 5 + 2x
2x + x - 3 = - 5 + 2x
3x - 3 = - 5 + 2x
3x - 3 - 2x = - 5
3x - 2x = - 5 + 3
1x = - 2
x = - 2/1
x = - 2

2x+3 (-x+1)=5

2x + 3(-x + 1) = 5
2x  - 3x + 3 = 5
 - 1x + 3 = 5
- 1x = 5 - 3
- 1x = 2
x = 2/-1
x = - 2/1
x = - 2

2x+3=x

2x + 3 = x
2x = x - 3
2x - x = - 3
1x = - 3
x = - 3/1
x = - 3

-b+3=b

- b + 3 = b
- b = b - 3
- b - b = - 3
- 2b = - 3
b = - 3/-2
b = + 3/2


c+2c=2+c

C + 2C = 2 + C
3c = 2 + c
3c - c = 2
2c = 2
c = 2/2
c = 1

-x=3x-5

- x = 3x - 5
- x - 3x = - 5
- 4x = - 5
x = - 5/-4
x = + 5/4

5+x=2x

5 + x = 2x
x = 2x - 5
x  - 2x = - 5
- 1x = - 5
x = - 5/-1
x = + 5/1
x = 5
 
2+3a=5a

2 + 3a = 5a
3a = 5a - 2
3a - 5a = - 2
- 2a = - 2
a = - 2/-2
a = + 2/2
a = 1

2a-3=10a 

2a - 3 = 10a
2a = 10a + 3
2a - 10a = + 3
- 7a = 3
a = 3 /-7
a = - 3/7

4x-1=x

4X - 1 = X
4x = x + 1
4x - x =  + 1
3x = 1
x = 1/3

 
x=2x+3x  

x  = 2x + 3x
x = 5x     ( valor igualar a ZERO)
x - 5x = 0
- 4x = 0
x = 0/-4
x = - 0/4
x = 0
