Answer 1

Answer:

c. 13 is the right answer.

Answer 2

Answer:-

Given equation

4x - 3 = 21

To find =>

3x - 5 = ?

Now,

Let's find the value of x,

$\begin{gathered}4x - 3 = 21 \\ 4x = 21 + 3 \\ 4x = 24 \\ x = \frac{24}{4} = 6\end{gathered}$

4x−3=21

4x=21+3

4x=24

x= 4

24 =6

x = 6

Now,

Put the value of x in the equation..

3x - 5

$\begin{gathered}3(6) - 5 \\ = 18 - 5 \\ = 13\end{gathered}$

3(6)−5

=18−5

=13

Thus,

3x - 5 = 13.
