how do you solve the equation. Remember to check for extraneous solutions. x_2x-6=2_x-4?

Well Di,

i have to realize that even with the brackets,

i do not understand.... in classical maths language.

Therefore... let's imagine what it might mean...

(like with Judy Foster in the film "Contact" !)

then, i would say that:

if, in place of the first underscore, we have a "+" then we obtain :

x + 2x - 6 = 3x - 6 = 3(x - 2)

and

if, in place of the second underscore, we have a " . " (multiplication)

then we get :

2 . x - 4 = 2(x - 2)

but now...

... my mind is some kinda lost somewhere in the gallaxy !

second trial :

(x_2x-6)=(2_x-4)

might mean an equation : still with a plus and multiplication, giving:

x + 2x - 6 = 2x - 4

which leads to

x + 2x - 6 - 2x = 2x - 4 - 2x

x - 6 + 6 = - 4 + 6

finally:

x = 2

;-)

et voilà !!

hope it' ll help !!
