Question

Complete the activity to find the value of

3 + 2 = 11 −---- (I) and 2 + 3 = 4 ------(II)

Solution: Multiply equation (I) by ----- and equation (II) by -----.

× (3 + 2 = 11) ∴ 9 + 6 = 33

2 × (2 + 3 = 4) ∴ 4 + 6 = 8

subtract (II) from (I),

----- = 25

∴ = ----

4) If (2, 0) is the solution of 2x + 3y = k then finds the value of k by

completing the activity

Solution: (2,0) is solution of the equation 2x +3y = k

Putting x =

and y =



∴ 2(

) + 3 × 0 = k​
