<em><u>Answer:</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>13 and 5</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>Step-by-step explanation:</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>x+y=18</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>x-y=8</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>_____</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>2x=26</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>x=13</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>So the first number must be 13</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>13+y=18</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>y=5</u></em>
<em><u></u></em>
<em><u></u></em>
<u><em>And the second number must be 5</em></u>
When you graph a system of equations, the solution is always at the point at which the two lines intersect. So you have to find that point and then find which number it is on the x-axis and y-axis. Then you should write it in this form (X,Y)
So the lines basically cross at (1,2.5)
I’m not really sure if this is the correct answer but I hope it helps!!
Good luck!
