Question

Verify the following : 8) 0.3 + 0.7x = 0.85x ?

Answer 1

0.3 + 0.7x =0.85x

0.85x-0.7x=0.3

0.15x=0.3

x=0.3/0.15

x=2

Answer 2

Solution:

_____________________________________________________________


Given & To verify:

0.3 + 0.7x = 0.85x ....(i)

_____________________________________________________________

As, if we bring coefficients of x(including x) RHS,

we shall get the value of x,

=> 0.3 + 0.7x = 0.85x

=> 0.7x - 0.85x = -0.3

=>  -0.15x = -0.3

=> x = 2,.

If x = 2, this equation is correct (and verified),

there is no possible value of x then 2 to have this equation (i) possible...
