a = 2 and b = 0.​

Answer 1

$\huge{\rm{\color{gold}{Question:-}}}$

Evaluate the expression ( 3a + 2b ) - 12, where a = 2 and b = 0.

$\huge{\rm{\color{gold}{Solution:-}}}$

Substituting the values of a and b ( a = 2 , b = 0 ) in ( 3a + 2b ) - 12 :-

==> [ 3(2) + 2(0) ] - 12

==> ( 6 + 0 ) -12

==> 6 - 12

==> -6

Therefore, the value of ( 3a + 2b ) - 12 when a = 12, b = 0 is -6.

Answer 2

Answer:

Substituting the values of a and b ( a = 2 , b = 0 ) in ( 3a + 2b ) - 12 :-

==> [ 3(2) + 2(0) ] - 12

==> ( 6 + 0 ) -12

==> 6 - 12

==> -6

$\begin{gathered} \\ \\ \end{gathered}$

Therefore, the value of ( 3a + 2b ) - 12 when a = 12, b = 0 is -6.
