Answer:
x = 14
y = 11
Explanation:
x - y = 3
2x + 2y = 50
multiplty x - y = 3 by two so we can get an equal value
2x - 2y = 6
2x + 2y = 50
-2y and 2y can be cancled out. That means we don't need to change any signs and we can add everything exept 2y and -2y becuase they will be cancled out.
4x = 56
Divide each side by 4 to leave x alone.
x = 14
Now that we know the x value, take one of the equations in the question and plug it in. I am going to use the equation x - y = 3 to make it easier.
14 - y = 3
-y = 3 - 14
-y = -11
y = 11
Now we know that y = 11.
I hope this helps!
