Division. You can divide 64 by 3 to find q.
8x+y=3
-8x -8x
--------------
y=-8x+3
7x-2y=-6
-7x -7x
------------------
-2y=-7x-6
----- -------
-2 -2
y=7/2x+3
Substitute -8x+3 in place of y
-8x+3=7/2x+3
+8x +8x
-----------———
3= 11.5x+3
-3 -3
———————
0 = 11.5x
—— ——
11.5 11.5
X=0
8x+y=3
8(0)+y=3
0+y=3
y=3
Check
8(0)+3=3
7(0)-2(3)=-6
0-6=-6
