Answer 2

Answer :

Given :

• The value of k is k+7=10

Find :

• The value of 9k - 50

Solution :

☘ Let us, first find the value of k

= k + 7 = 10

= k = 10 - 7

= k = 3

•°• From here, we have the value of k = 3

Now,

• Put k = 3 in the given expression

= 9k - 50

= 9(3) - 50

= 27 - 50

= -23 $\;$

•°• The value of 9k - 50 is -23 respectively.
