Question

Read the given paragraph carefully and answer the questions accordingly:

A boy was getting bored . He decided to utilize his time in a constructive manner . He wrote five different linear equations in two variables on five cards and placed them in a box . Answer the following questions according to his experiments :
equation 1 : 2x+3y=18
equation 2 : -7x+9y=15
equation 3 : 6x+5y=-34
equation 4 : 4x+2y=0
equation 5 : 3x+4y=5

Q-1 The boy picked three cards at random . The cards were of equations 1 , 3 and 5 . He added equations 1 and 3 and got a new equation . Now he found the ratios of the coefficients of this new equation and of equation 5 . According to this condition , the lines were.

Q-2 He subtracted equations 1 and 3 . Now he found the ratios of the coefficients of the resulting equation and equation 4 . According to this condition , the lines were.

Q-3 He added equations 1 , 4 and 5 . He doubled the constant of the resulting equation and added it to the constant of equation 3 . According to this , his answer should be.

Q-4 He multiplied equation 1 by numeric number 2 . He solved the resulting equation and equation 4 for x and y . The values of x and y should be.

Q-5 He added all the equations , the coefficient of y of the resulting equation should be.

Answer 1

Answer:

It depends on the field of training, of course. But, I think, the general rules are as follows:

1. Know and love your own subject. Anyone who does not like their subject cannot activate students.

2. Make difficult questions for students simple. In the presentation of abstract questions it is necessary to "include" imagery. Then understanding improves. What you understand is more interesting.

3. Try to link problems to the experience of students.

4. Arrange provocations: sometimes formulate questions in such way as to cause a desire to challenge the point of view expressed by the teacher.

5. Show that the result depends on the efforts of students.
