Answer 2

Value of x is 2.

Given:

• An equation.
• $7x + 4 + x = 14 + 3x$

To find :

• Find the value of x.

Solution:

Step 1:

Take all terms of x in LHS and constant terms to RHS.

$7x + x - 3x = 14 - 4$

Add 7x and x, and subtract 14 and 4.

$8x - 3x = 10$

Subtract 3x from 8x,

$5x = 10$

Step 2:

Solve the equation for x.

Cross multiply 2 to the other side.

$5x = 10$

Divide 10 by 5.

$x = \frac{10}{5}$

$\bf x = 2$

Thus,

Value of x is 2.
