Answer 2

Answer :-

Value of x = 3.

Explanation :-

Given Equation :

• 8x - 4 = x + 17.

To find :

• Value of x.

Solution :

Use the method of transposition here.

In this method, sign conversion appears. These signs are changed only when the variables or the coefficients are taken to the opposite ides.

Such that,

+ changes to –

– changes to +

× changes to ÷

÷ changes ×

➨ 8x - 4 = x + 17.

➨ 8x - x = 17 + 4.

➨ 7x = 21.

➨ x = 21 ÷ 7.

➨ x = 3.

Therefore, Value of x = 3.

Verification / Check :

➨ 8(3) - 4 = 3 + 17.

➨ 24 - 4 = 20.

➨ 20 = 20.

LHS = RHS.

Hence, Verified.
