Answer 2

Answer:

this system of equation have no solution .

Step-by-step explanation:

here a1 = 2,b1 =2 c1 =5

a2 = 3,b2 = 3, c2 =7

in this we can see that a1 by a2 equal to b1 by b2

but not equal to c1 by c2

this type of comparison of ratios happens in parallel lines and parallel lines have no solution

so in this equation there is no solution
