0.3x-1.1-x=0.3 Start with the given equation.


10%280.3x-1.1-x%29=10%280.3%29 Multiply both sides by 10 to clear out the decimals.


3x-11-10x=3 Distribute and multiply.


-7x-11=3 Combine like terms on the left side.


-7x=3%2B11 Add 11 to both sides.


-7x=14 Combine like terms on the right side.


x=%2814%29%2F%28-7%29 Divide both sides by -7 to isolate x.


x=-2 Reduce.

Can combine like terms (the x's):
-0.7x-1.1=0.3
Then move the 1.1 over by adding it:
-0.7x=1.4
Divide both sides by -0.7:
x=-2, which is our answer.
