Question

0.5x + 1.5 = 0.7x - 0.9​

Answer 1

Step-by-step explanation:

0.5x+1.5=0.7x-0.9

0.7x-0.5x=1.5+0.9

0.2x=2.4

x=12

Answer 2

The value of x = 12

Correct question : 0.5x + 1.5 = 0.7x - 0.9. Find the value of x

Given :

$\displaystyle \sf{ 0.5x + 1.5 = 0.7x - 0.9 }$

To find :

The value of x

Solution :

Step 1 of 2 :

Write down the given equation

Here the given equation is

$\displaystyle \sf{ 0.5x + 1.5 = 0.7x - 0.9 }$

Step 2 of 2 :

Find the value of x

$\displaystyle \sf{ 0.5x + 1.5 = 0.7x - 0.9 }$

$\displaystyle \sf{ \implies 0.5x - 0.7x = - 0.9 - 1.5}$

$\displaystyle \sf{ \implies - 0.2x = - 2.4}$

$\displaystyle \sf{ \implies x = \frac{ - 2.4}{ - 0.2} }$

$\displaystyle \sf{ \implies x = \frac{ 2.4}{ 0.2} }$

$\displaystyle \sf{ \implies x = \frac{ 2.4 \times 10}{0.2 \times 10} }$

$\displaystyle \sf{ \implies x = \frac{ 24}{2} }$

$\displaystyle \sf{ \implies x = 12}$

Hence the required solution is x = 12
