Question

3(4x-5)=5(2x-5) please answer​

Answer 1

Answer:

Given :

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

To find :

$\textsf{The value of x in this equation}$

Concept :

Use the cross multiplication formula to find the values of the bracket .And then do the x integer with x . And the - integer with - integer .

Solution :

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

Used cross multiplication.

$\sf:\implies{12x-15=10x-25}$

Solving x with x and - integer with - integer

$\sf:\implies{12x-10x=-25+10}$

$\sf:\implies{2x=-15}$

Now , divide

$\sf:\implies{x=\dfrac{-15}{2}}$

$\sf:\implies{x=-7.5}$

So , the value of x is -7.5 .

Answer :

Value of x in the following equation -:

$\sf:\implies{-7.5}$

Answer 2

Answer:

$3(4x - 5) = 5(2x - 5) \\ \\ = 12x - 15 = 10x - 25 \\ \\ = > 12x - 10x = - 25 + 15 \\ \\ = > 2x = - 10 \\ \\ = > x = \frac{ - 10}{2} = - 5$
