Answer 1

Resposta:

2x/6= 3x+5/10,5

18x+30= 21x

18x-21x= -30

-3x= -30

x= -30/-3

x= 10

--------------------

b) 10/3x= 15/4x+1

45x= 40x+ 10

45x-40x= 10

5x= 10

x= 10/5

x= 2

---------------------------

c) 20/25=28/x= y/40

20x= 25*28

20x= 700

x= 700/20

x= 35

---------------------

20/25= y/40

25y= 20*40

25y= 800

y= 800/25

y= 32
