Answer 1

Given

x = 4(x+10)/5

Using Cross multiplication

5x = 4(x + 10)

5x = 4x + 40

5x - 4x = 40

x = 40

Answer

x = 40

Now Verify Our answer

x = 4(x+10)/5

Using Cross multiplication

5x = 4(x + 10)

5(40) = 4(40 + 10)

200 = 4(50)

200 = 200

Answer 2

Answer:

Given :-

$\mapsto$ $\sf x =\: \dfrac{4}{5}\: (x + 10)$

To Find :-

$\mapsto$ What is the value of x.

Solution :-

$\longrightarrow$ $\sf x =\dfrac{4}{5}\: (x + 10)$

$\implies$ $\sf x =\: \dfrac{4(x + 10)}{5}$

$\implies$ $\sf x =\: \dfrac{4x + 40}{5}$

By doing cross multiplication we get,

$\implies$ $\sf 5x =\: 4x + 40$

$\implies$ $\sf 5x - 4x =\: 40$

$\implies$ $\sf\boxed{\bold{x =\: 40}}$

$\therefore$ The value of x is 40 .
