-x-3=0.8-10x
To find the opposite of x+3, find the opposite of each term.
-x-3+10x=0.8
Add 10x to both sides.
9x-3=0.8
Combine -x and 10x to get 9x.
9x=0.8+3
Add 3 to both sides.
9x=3.8
Add 0.8 and 3 to get 3.8.
x=\frac{3.8}{9}
Divide both sides by 9.
x=\frac{38}{90}
Expand \frac{3.8}{9} by multiplying both numerator and the denominator by 10.
x=\frac{19}{45}
Reduce the fraction \frac{38}{90} to lowest terms by extracting and canceling out 2.
