$3x + 4 = 5(x - 2)$

$3x + 4 = 5x - 10$

$4 + 10 = 5x - 3x$

$14 = 2x$

$x = \frac{14}{2} = 7$

Answer 2

Answer :

›»› The value of x = 7

Given :

• 3x + 4 = 5(x - 2)

To Find :

• The value of x = ?

Required Solution :

Let's start solving the equation and understand the steps to get our final result for x$.$

⇛ 3x + 4 = 5(x - 2)

Multiply each term in paranthe by 5,

⇛ 3x + 4 = 5x + 5 × (-2)

Multiply 5 and -2,

⇛ 3x + 4 = 5x - 10

Move the variable to left-hand side and change the symbol,

⇛ 3x - 5 = -10 - 4

Calculate between similar term,

⇛ -2x = -10 - 4

Find the sum of negative numbers,

⇛ -2x = -14

Change the sign of both sides of the equation,

⇛ 2x = 14

Divide both sides by the same number,

⇛ x = 14/2

Divide 14 by 2,

⇛ x = 7

║Hence, the value of x is 7.║
