Answer:

the answer is x equals 22 and y equals 8

Step-by-step explanation:

first equation is x+y=30

Second equation is x-y/2=7 that simplify's to x-y=14

then you add then so they will cancel out and you are left with 2x=44 so divide two by both sides which gives x=22

then you subsitute the 22 in the first equation. It will be 22+y=30 then you subtract 22 from the 30 that gives you y=8

so the two numbers are 22 and 8

Hope this helps!!!!
