I dont know the answers to this question please tell me the x and y

x = -5 y = 5

Step-by-step explanation:

=> -7x - 2y = 25

            -4x - 9y = -25

=> 4(-7x - 2y = 25)

             7(-4x - 9y = -25)

=> -28x - 8y = 100

            -28x - 63y = -175

=> 55y = 275=> y = 5

Now, let's substitute the value of y into the first equation.

=> -7x - 2y = 25=> -7x - 2(5) = 25=> -7x - 10 = 25=> -7x = 35=> x = -5

Now, let's check our answer to make sure our answer is correct.

Check:

-4x - 9y = -25=> -4(-5) - 9(5) = -25=> 20 - 45 = -25=> -25 = -25

Hence, this is proved correct.

Hoped this helped.
