Simplify the algebraic expression by combining similar terms.
x - 0.8x - 2.9x
in this case what is x on it's own

Just break it into parts. X=1x. X can be any other variable but the thing that matters is that all the variables are the same. 1x-.8x=.2x. Then .2x-2.9x= -2.7x. It simplifies down to -2.7x but there is know way to figure out what the value of X is. If the equation was x-.8x-2.9x=any thing a value for x would be possible to find but there is known and so there is no way to find the value of x on it's own.

Just combine like terms:
0.2x-2.9x=-2.7x

just add coeficients
x - 0.8x - 2.9x
1x-.8x-2.9x=(1-.8-2.9)x=-2.7x

x - 0.8x - 2.9x = x - 3.7x
= 1x - 3.7x
= -2.7x

x - 0.8x - 2.9x
1x - 0.8x - 2.9x
0,2x - 2.9x = - 2.7x
The answer is = - 2.7x
- - - - - - - - -s-

x - 0.8x - 2.9x = (1 - 0.8 - 2.9)x = -2.7x

yeah it's -2,7x jus subtract it all without forgetting that x on its own is the same as 1x

X on its own is the same as 1x or 1.0x

this is 6th grade math the answer is -2.7.
and yes x is on it's own but it is also considered 1x or 1.0x if your dealing with decimals.

Just subtract. 1 - 0.8 - 2.9 = -2.7x
