0,64x=x+0,09 How can i solve it?
0.64x = x + 0.09 it makes it easier if you multiply through by 100....so we have
64x = 100x + 9 subtract 100x from both sides
-36x = 9 divide both sides by -36
x = -9 / 36 = -1/4
combine like terms.combine 0,064x and x. there is a 1 infront of the x that you can not see so what you will do is add the two you will get 0,065x + 0,09 . just remember that there is a ivisable 1 beforea x that is singular
