Question

What is the solution of the equation? 4.7x 3.8 = 13.2 a. 3.7 b. 3 c. 2 d. 3.6?

Answer 1

Answer:  The correct option is (c) 2.

Step-by-step explanation:  We are given to find the solution of the following equation :

$4.7x-3.8=13.2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To solve the given equation, we need to find the value of the unknown variable x.

The solution of equation (i) is given by

$4.7x+3.8=13.2\\\\\Rightarrow 4.7x=13.2-3.8\\\\\Rightarrow 4.7x=9.4\\\\\Rightarrow x=\dfrac{9.4}{4.7}\\\\\Rightarrow x=2.$

Thus, the required solution is x = 2.

Option (c) is CORRECT.

Answer 2

Assuming that the equation is 4.7x+3.8=13.2:
 4.7x=9.4 - isolate x on one side
x=2 - divide 9.4/4.7 to solve for x
The answer is C.
