Question

If 4x-3 =21 , what is the value of (3x-5) ?



please answer fast dear​

Answer 1

Answer:

4x-3=21

=>4x=21+3

=> 4x=24

=> x=24/4

=> x=6

so,

3x-5

=3.6-5

=18-5

=13

Answer 2

Answer:

To find the value of 3x - 5, we have to first find the value of x.

4x - 3 = 21

⇒ 4x = 21 + 3

⇒ 4x = 24

⇒ x = $\frac{24}{4}$

⇒ x = 6

Now that we have found out the value of x, we can now solve 3x - 5 by substituting x with 6.

⇒ 3x - 5

⇒ 3(6) - 5

⇒ 18 - 5

⇒ 13

Hence, 3x - 5 is equal to 13 where x is equal to 6.

Thnx and have a nice day!
