Here you have to matrix addition mean you have to simple add corresponding elements of the matrices.

For eg.

[ a b] + [c d] = [a+c b+d]

Similarly, you can add corresponding elements for any order.

Just make sure to add a11 with b11

a12 with b12

a21 with b21

a22 with b22 and soon.

Let cost of apples be rs x Let cost of grapes be Rs y A. T. Q 2x+1y=160 ---------- 1 4x+2y=300 ---------- 2

Archana Bhandari 3 years, 10 months ago

Let cost each kg of apples = Rs x Cost of each kg of grapes = Rs y Given that the cost of 2 kg of apples and 1kg of grapes on a day was found to be Rs 160 So that 2 x + y = 160 … (i) 2x = 160 - y x = (160 – y)/2 Let y = 0 , 80 and 160, we get x = (160 – ( 0 )/2 = 80 x = (160- 80 )/2 = 40 x = (160 – 2 × 80)/2 = 0 x 80 40 0 y 0 80 160 Given that the cost of 4 kg of apples and 2 kg of grapes is Rs 300 So we get 4x + 2y = 300 … (ii) Dividing by 2 we get 2x + y = 150 Subtracting 2x both side, we get y = 150 – 2x Putting x = 0 , 50 , 100 we get y = 150 – 2 × 0 = 150 y = 150 – 2 × 50 = 50 y = 150 – 2 × (100) = -50 x 0 50 100 y 150 50 -50 Algebraic representation, 2x + y = 160 … (i) 4x + 2y = 300 … (ii) Graphical representation, Graph 3
