Question

$6x + 4x + 10 \div 20 = 4 \div 5$
​

Answer 1

Answer:

6x+4x+10÷20=4÷5

= 10x+ 0.5= 0.8

10x= 0.8-0.5

10x= 0.3

x= 0.3/10 ( 3/100)

so x= 3/100 or 0.03 ( both values are equal)

Answer 2

AnswEr:-

Given:-

$\tt\longrightarrow 6x+4x+10\div 20= 4\div5. \\ \\ \tt\longrightarrow 10x+10\div20 = 4\div5$

To Find:-

• The value of x.

So lets solve the given equation:-

$\tt\mapsto10x+10\div20 = 4\div5. \\ \\ \tt\mapsto10x+0.5 = 0.8 \\ \\ \tt\mapsto 10x = 0.8-0.5 \\ \\ \tt\mapsto 10x = 0.3 \\ \\ \tt\mapsto x = \dfrac{0.3}{10} \\ \\ \tt\mapsto x = \dfrac{3}{100} \\ \\ \tt\mapsto x = 0.03$

$\therefore$ The required value of x is 0.03.

VerificaTion:-

Let us put the value of x in given equation.

$\tt\longrightarrow 10x+10\div20=4\div5 \\ \\ \tt\longrightarrow 10(0.03)+0.5 = 0.8\\ \\ \tt\longrightarrow 0.3+0.5 = 0.8 \\ \\ \tt\longrightarrow 0.8 = 0.8 \\ \\ \tt\longrightarrow LHS=RHS$

Hence Verified
