Hi
can someone check is my problem is right
Q. If four times julio's age is decreased by 50, the result is twice Julio's age. How old is Julio?
A.
4x- 50 = 2x
-4x -4x
-50= -2x
Divide -50/-2
X=25
now that I fond x=25 I multiply by 2
2(25)=50
Thank you

x is julio's age, so you don't have to multiply by 2.
Julio's age is 25.

you did the math right, but you don't need to multiply by 2 at the end. x is julio's age... julio is 25. You can always double check your answer to see if it makes sense. Four times julio's age is 100 and twice julio's age is 50, which makes the problem work.

No. Julio is x years old = 25
4*25 -50 = 50 which is twice 25

x=25 is Julio's age. mot 2x=50, which is twice Julio's age.

So close!
You're letting x = Julio's age, so when solving to x = 25, you're done.

4x - 50 = 2x
4x - 2x = 50
2x = 50
x = 25
