18 x (x)=126

x=126 divided by 18

x=7

therefore,

x=7

Step-by-step explanation:

Answer 2

Given:-

• 3, 18, x, 42 are in the proportion.

⠀

To find:-

• Value of x.

⠀

Solution:-

• Let's do it

⠀

⇛ 3:18::x:42

⇛ 3 × 42::18 × x

⇛ 126::18x

⇛ 126/18 = x

⇛ x = 7

⠀

Hence,

• the value of x is 7.

⠀

Verification:-

⇛ 3:18::7:42

⇛ 3 × 42::18 × 7

⇛ 126::126

Hence Verified
