<h2>
The value of x = - 
</h2>
Step-by-step explanation:
The given expressiona are:
and 
To find, the value of x = ?
∴ 
By crossmultiplication, we get
4(3x + 2) = 2(3x - 6)
⇒ 12x + 8 = 6x - 12
⇒ 12x - 6x = - 12 - 8
⇒ 6x = - 20
⇒ 3x = - 10
⇒ x = - 
∴ The value of x = - 
Thus, the value of x is equal to -
.
Commutative property of multiplication is shown above. This is because no matter how you put them, the answer will still be 140.
