0.6\left(x-2\right)-0.3\left(x+3\right)-\left(2x-5\right)+9=0
Multiply both sides of the equation by 3.
0.6x-1.2-0.3\left(x+3\right)-\left(2x-5\right)+9=0
Use the distributive property to multiply 0.6 by x-2.
0.6x-1.2-0.3x-0.9-\left(2x-5\right)+9=0
Use the distributive property to multiply -0.3 by x+3.
0.3x-1.2-0.9-\left(2x-5\right)+9=0
Combine 0.6x and -0.3x to get 0.3x.
0.3x-2.1-\left(2x-5\right)+9=0
Subtract 0.9 from -1.2 to get -2.1.
0.3x-2.1-2x-\left(-5\right)+9=0
To find the opposite of 2x-5, find the opposite of each term.
0.3x-2.1-2x+5+9=0
The opposite of -5 is 5.
-1.7x-2.1+5+9=0
Combine 0.3x and -2x to get -1.7x.
-1.7x+2.9+9=0
Add -2.1 and 5 to get 2.9.
-1.7x+11.9=0
Add 2.9 and 9 to get 11.9.
-1.7x=-11.9
Subtract 11.9 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-11.9}{-1.7}
Divide both sides by -1.7.
x=\frac{-119}{-17}
Expand \frac{-11.9}{-1.7} by multiplying both numerator and the denominator by 10.
x=7
Divide -119 by -17 to get 7.
