Question

encuentra el valor de "x"
5x+2=x+6
20x+2=7x
3x+1=2x+4

Answer 1

5x + 2 = x + 6

5x - x = 6 - 2

4x = 4

x = 4/4

x = 1
---------------------------------

20x + 2 = 7x

20x - 7x = - 2

13x = - 2

x = - 2/13
-----------------------------------

3x + 1 = 2x + 4

3x - 2x = 4 - 1

x = 3 

Answer 2

5x+2=x+6
4x=4
x=1

20x+2=7x
13x=-2

3x+1=2x+4
x=3
