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

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.

Answer 2

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=(9.4)/(4.7)\\\\\Rightarrow x=2.`

Thus, the required solution is x = 2.

Option (c) is CORRECT.
