1. A = {ANKARA} B = {}, C={Haftanın A harfi ile başlayan günleri}
ise s(A) + S(B) + s(C) toplamı kaçtır?

If a solution exists, the (x,y) coordinates will be equal, so we can say y=y:

7x-8=5x-2  add 8 to both sides

7x=5x+6  subtract 5x from both sides

2x=6  divide both sides by 2

x=3, now substitute this value for x into either original equation to solve for y

y=5x-2 becomes:

y=5(3)-2

y=15-2

y=13

So the solution to the system of equations is the point:

(3, 13)
