Let the numbers be x and y.  Write out mathematical equations:

y=2x         and             x+y=36

You were not asked to solve this problem, but should do so for practice.  Subst. 2x for y in the 2nd equation:  x + 2x = 36;    3x = 36;     x = 12.  Find y.  Then check your solution.

Let

y------>one number

x------> another number

we know that

y=2x ------> equation A

x+y=36 ------> equation B

substitute equation A in equation B

x+2x=36

3x=36

x=12

Find the value of y

y=2x

y=2*12=24

the numbers are 24 and 12

therefore

<u>the answer is</u>

The system of equations are

x+y=36 and y=2x
