Question

the value of the expression 10 y - 20 depends on the value of y. verify this by giving five different values to y and finding for each why the value of 10 y - 20. from the different values of 10 y - 20 you obtain do you see a solution to 10 y - 20 is equal to 50? if there is no solution try giving more values to y and find whether the condition 10 y - 20 is equal to 50 is met​

Answer 1

Answer:

(i) Let y = 2 . We have :

(ii) Let y = 3 . We have :

(iii) Let y = 4 . We have :

(iv) Let y = 5 . We have :

(v) Let y = 6 . We have :

Hence 10y - 20 depends upon y.

Now, consider

Transpose - 20 to the RHS :
