Question

if 4x-3 = 21 what is the value of(5x-5)​

Answer 1

Answer:

25

Step-by-step explanation:

$4x - 3 = 21 \\ = > 4x = 21 + 3 \\ = > 4x = 24 \\ = > x = \frac{24}{4} \\ = > x = 6 \\ \\ now \: \\ 5x - 5 = 5(6) - 5 = 30 - 5 = 25$

Answer 2

Answer:

4x-3 = 21

4x = 21 + 3

4x = 24

x = 24

4

x = 6

5x-5 =? Let the value to be found be a

5 ×(6) - 5 = a ( since x = 6)

30-5=a

25 = a
