Good evening. The first statement can be written mathematically this way: y=4x-6

The second part can be written as x+y=14

If you substitute the first for the second (the 4x-4 for the y in the second equation), you get

x + (4x-6) = 14 and you can simplify

5x -6 = 14

Add 6 to both sides to maintain the equality

5x=20

Divide by 5

x=4

Now plug 4 into one of the initial equations:

4 + y = 14 and solve

Subtract 4 from both sides and you get

y = 10

So the numbers are 4 and 10

Hope this helps

Mike
