Yes.
Question 2.
Can you form a chain going from the bottom equation to the top? Compare the operations used when going from the top to the bottom and from the bottom to the top. Class 7
Solution:
Yes.
Question 3.
Without calculating, can you find the value of the unknown in each equation in the chains above? Class 7
[Hint: We have seen that the value that satisfies an equation also satisfies the new equation obtained by performing the same operation on both sides of the original equation.]
Solution:
Yes, as already explained in hint above.
