Question 1006187
x+y+z= 119
y= 2x
z= 2y 
----------------
y= 2x multiply both sides by 2:
2y= 4x Since we said that:
z= 2y and:
2y= 4x then:
z= 4x
Let's write our equation with one variable:
------------------------
x+2x+4x= 119 Add x on left:
7x= 119 Divide both sides by 7:
x= 17 is your first number
2(17)= 34 is your second number
4(17)= 68 is your third and Largest number
Proof:
17+34+68= 119
119= 119 We have the correct answer
