Answer 2

Answer:

Value of x or the answer of the equation is 7 .

Step-by-step explanation:

Given :

3x+4=5(x-2)

To find :

Find the value of x

Concept :

In the question do the cross multiplication in 5(x-2) .

And then after add or subtract the x and the number then divide the number from the x . Then , we will get the value of x .

Solution :

$:\implies\sf{3x+4=5(x-2)}$

$:\implies\sf{3x+4=5x-10}$

$:\implies\sf{4+10=5x-3x}$

$:\implies\sf{14=2x}$

$:\implies\sf{\dfrac{14}{2}=x}$

$:\implies\sf{7=x}$

So , the value if x is 7 .
