Answer 2

Given equation:

• 4x + x + 3 = 8

To find:

• Value of x.

Solution:

4x + x + 3 = 8

5x + 3 = 8

5x = 8-3

5x = 5

x = $\sf \dfrac {5}{5}$

$\boxed {\mathfrak {\red {x = 1}}}$

Verification:

LHS = 4x + x + 3

RHS = 8

Substitute the value of x as 1 in the equation,

4x + x + 3 = 8

4×1 + 1 + 3 = 8

4 + 1 + 3 = 8

8 = 8

LHS = RHS

Hence Verified!

Value of x:

Value of x is 1.
