Question

solve the problem please
a)7y+5=19 (y=2)
b) 3k+9=5 (k=7)
​

Answer 1

Answer:

A

A) 7y+5=19 (y=2)First put the value ::

If y =2 then 7y=7x2

So,,7x2 + 5=19

14+5=19

19=19Hence proved LHS=RHS.

B) 3k+9=5(k=7)Same here also,, put the values

If k=7Then 3k= 3x7

So,3x7+9=5

21+9=5

30 is not equal to 5

Hence proved LHS IS NOT EQUAL TO RHS
