Question

Solve for x and y. 2x+5y=30 and 3x-2y=7​

Answer 1

Answer:

let 2x+5y=30 be 1st eq.

and other be 2nd eq.

now multiplying by 3 in eq.1

=6x+15y=60

same in eq2.by 2

=6x-4y=14

substract now outcomes of eq.1 and eq.2 and you will get value of y

Answer 2

Answer:

Let 2x + 5y = 30 be 1st eq

and other be 2n eq

Now multiplying by 3 in eq 1

= 6x + 15y = 60

Same in eq 2. by 2

Subtract now out comes of eq 1.And eq2 and you will get value of y
