Question

What value of n will make the equation 4n – 2 = 18 true?
​

Answer 1

Solution:

• 4n – 2 = 18 ... (1)

• 4n = 18 + 2

• 4n = 20

• n = 20/4

• n = 5

verification:

Put n=5 in equation (1)

• 4(5) - 2 = 18

• 20 - 2 = 18

• 18 = 18

So

• 5 value of n will make the equation 4n – 2 = 18 true.

Answer 2

Answer:

n=5

Step-by-step explanation:

4n-2=18

L. H. S

by placing 5 in n's place we get,

(4x5) -2 = 20-2 =18

R. H. S

18

THEREFORE, it is proved that n=5
