Hello!
To check your work what you do is you put 3 in for x and 7 in for y and see if you get the same answer on both equations.
Hope this helps!
3 multiplied by 4 is 12
<span>3 multiplied by 7 is 21 </span>
<span>that is how the photos are split 4:7</span>
Sorry no answer just wanted to say your pfp is hot
Don’t you just add them? So it is 200?
