Question

I find the product
- 100x56=50X C-100​

Answer 1

Answer:

Step-by-step explanation:

Hii There!!!

Let the given equations be equation 1) and 2)

Now, multiply eq. 1) by 50 and eq.2) by 100

We get :-

50 × [ 100x + 50y = 2500 ]

=) 5000x + 2500y = 125000 ------3)

Similarly, 100 × [ 50x + 100y = 2000]

=) 5000x + 10000y = 200000 ----4)

So, solving eq. 3) and 4) by elimination method

we get ,

5000x + 2500y = 125000

5000x + 10000y = 200000

-. -. -

_____________________

=) -7500y = - 75000

=) y = 10

Now, put value of 'y' in eq 1)

100x + 50 × 10= 2500

=) 100x +500 =2500

=) 100x = 2000

=) x = 20

Hope it helps
