The ‘Solve

Solve the equation (i) for y.

=> 9x + 3y = 6

=> 3y = 6 – 9x

=> y = 2 – 3x [ On dividing both the sides by 3]

Substitute the value of y in the equation (ii) , we will get :

=> 2x + 3y = 7

=> 2x + 3(2 – 3x) = 7

=> 2x + 6 - 9x = 7

=> -7x + 6 = 7

=>-7x = 7 – 6

So here we will get the value of x = - 1/7 and now we will solve for y ,we will put the value of x in the equation y = 2-3x , here we will get

=> y = 2- 3( -1/7) = 2 + 3/7 = 17/7

Solution: Here for the given equations :

Adding the equations (i) and (ii), we get

=> 2x = 48

Dividing the equation by 2

=> x = 24

Here , we will solve for y , by plugging the value x = 24 in equation (i)

=> x+ y = 35

=> 24 + y = 35

=> y = 35 - 24 = 11
