Question

the solution of 11x 89y=200 and 89x+111y=200​

Answer 1

SO WE NEED TO FIND THE ANSWER OF THE GIVEN QUESTION,

SO LET US START.

SOLUTION

Given,Equations are.

1. 11x+89y=200

2. 89x+11y=200

For solving,we must make 1 variable cancelled out .For doing that we are going to simplify the whole equation by adding the equation 1 and 2 to get a simplified equation from which we will find a value of one variable.

So, Eq(1)+Eq(2)

=》 11x+89y+89x+11y=200+200

=》 100x+100y=400

=》 x+y=4

=》 x=4-y

Now, we will substitute the value of x in any of the two equations.Let us substitute it in Eq 1

Now,

By substituting value of x in Eq(1) we have,

=》11×(4-y)+89y=200

=》44-11y+89y=200

=》78y=156

=》y=2

As we have got the value of y ,then value of x must be

equal to 4-y=4-2=2

Therefore,

Value of x=2, and y=2.
