Question

a soma do sextuplo de x co a terça parte de y

Answer 1

6x+1/3y =0
6x= -1/3y
3.6x= -y
18x = -y
x= -y/18

6x+1/3y =0
6.(-y/18) +1/3y =0
-6y/18 + y/3 <--- vamos sair por MMC
-6y+ 6y
-----------
  18

y/18 
y= 18

6x+1/3y =0
6x+1/3.18 =0
6x +6=0
6x= -6
x= -6/6
x= -1

Portanto: x= -1; y= 18

6x+1/3y =0
6.-1+1/3.18=0
-6+6=0
