Question

CALCULE ¨Х¨
Х/3 ₊ 10=Х ₊ 20/3

Answer 1

X + 10 = 3x + 60/3

x + 10 = 30 + 20 

x = 40

Answer 2

X/3+10=x+20/3
x/3-x=20/3-10

x=3x/3
10=30/3

x/3-3x/3=20/3-30/3
(x-3x)/3=(20-30)/3
-2x/3= -10/3
-2x= -10/3(3)
-2x= -(10(3))/3
se cancelan los (3) y queda
-2x= -10
x= -10/-2
x=5

Comprobacion

x/3+10=x+20/3
5/3+30/3=5+20/3
(5+30)/3=15/3+20/3
35/3=(15+20)/3
35/3=35/3-->(Comprobado, x=5)
