0.6x+0.2x+0.06x=x
Combine 0.5x and 0.1x to get 0.6x.
0.8x+0.06x=x
Combine 0.6x and 0.2x to get 0.8x.
0.86x=x
Combine 0.8x and 0.06x to get 0.86x.
0.86x-x=0
Subtract x from both sides.
-0.14x=0
Combine 0.86x and -x to get -0.14x.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since -0.14 is not equal to 0, x must be equal to 0.
