Answer 1

Step-by-step explanation:

4x-3=21

4x=21+3

4x=24

x=24/4

x=6

The value of 3x-5 is

18-5

13

Answer 2

Given : 4X-3 = 21

To Find : Value of 3X-5

4X-3 = 21

4X = 21+3

X = 21+3/4

Substituting X = 21+3/4 in 3X-5

3X-5

3(21+3/4)-5

4{3(21+3/4)} -20

3(21+3) - 20

3(24)-20

72-20

52

Hence, the value of 3X-5 is 52.

Hope the above answer is correct and helps you.
