# Two numbers

We have two numbers. Their sum is 140. One-fifth of the first number is equal to half the second number. Determine those unknown numbers.

Result

x =  100
y =  40

#### Solution:

x+y=140
x/5 = y/2

x+y = 140
2x-5y = 0

x = 100
y = 40

Calculated by our linear equations calculator.

Leave us a comment of example and its solution (i.e. if it is still somewhat unclear...):

I just took x as 40 and y as 100 and it says I'm wrong :( Dr Math
Please read again: One-fifth of the first number is equal to half the second .... 40/5 is not equal 100/2 #### To solve this verbal math problem are needed these knowledge from mathematics:
