2\times \frac{0.3x+0.9}{0.5}-\left(x-5\right)-2\times \frac{0.03+0.02x}{0.03}=0
Multiply both sides of the equation by 2.
2\times \frac{0.3x+0.9}{0.5}-x-\left(-5\right)-2\times \frac{0.03+0.02x}{0.03}=0
To find the opposite of x-5, find the opposite of each term.
2\times \frac{0.3x+0.9}{0.5}-x+5-2\times \frac{0.03+0.02x}{0.03}=0
The opposite of -5 is 5.
2\left(\frac{0.3x}{0.5}+\frac{0.9}{0.5}\right)-x+5-2\times \frac{0.03+0.02x}{0.03}=0
Divide each term of 0.3x+0.9 by 0.5 to get \frac{0.3x}{0.5}+\frac{0.9}{0.5}.
2\left(0.6x+\frac{0.9}{0.5}\right)-x+5-2\times \frac{0.03+0.02x}{0.03}=0
Divide 0.3x by 0.5 to get 0.6x.
2\left(0.6x+\frac{9}{5}\right)-x+5-2\times \frac{0.03+0.02x}{0.03}=0
Expand \frac{0.9}{0.5} by multiplying both numerator and the denominator by 10.
1.2x+2\times \frac{9}{5}-x+5-2\times \frac{0.03+0.02x}{0.03}=0
Use the distributive property to multiply 2 by 0.6x+\frac{9}{5}.
1.2x+\frac{2\times 9}{5}-x+5-2\times \frac{0.03+0.02x}{0.03}=0
Express 2\times \frac{9}{5} as a single fraction.
1.2x+\frac{18}{5}-x+5-2\times \frac{0.03+0.02x}{0.03}=0
Multiply 2 and 9 to get 18.
0.2x+\frac{18}{5}+5-2\times \frac{0.03+0.02x}{0.03}=0
Combine 1.2x and -x to get 0.2x.
0.2x+\frac{18}{5}+\frac{25}{5}-2\times \frac{0.03+0.02x}{0.03}=0
Convert 5 to fraction \frac{25}{5}.
0.2x+\frac{18+25}{5}-2\times \frac{0.03+0.02x}{0.03}=0
Since \frac{18}{5} and \frac{25}{5} have the same denominator, add them by adding their numerators.
0.2x+\frac{43}{5}-2\times \frac{0.03+0.02x}{0.03}=0
Add 18 and 25 to get 43.
0.2x+\frac{43}{5}-2\left(\frac{0.03}{0.03}+\frac{0.02x}{0.03}\right)=0
Divide each term of 0.03+0.02x by 0.03 to get \frac{0.03}{0.03}+\frac{0.02x}{0.03}.
0.2x+\frac{43}{5}-2\left(1+\frac{0.02x}{0.03}\right)=0
Divide 0.03 by 0.03 to get 1.
0.2x+\frac{43}{5}-2\left(1+\frac{2}{3}x\right)=0
Divide 0.02x by 0.03 to get \frac{2}{3}x.
0.2x+\frac{43}{5}-2-\frac{4}{3}x=0
Use the distributive property to multiply -2 by 1+\frac{2}{3}x.
0.2x+\frac{43}{5}-\frac{10}{5}-\frac{4}{3}x=0
Convert 2 to fraction \frac{10}{5}.
0.2x+\frac{43-10}{5}-\frac{4}{3}x=0
Since \frac{43}{5} and \frac{10}{5} have the same denominator, subtract them by subtracting their numerators.
0.2x+\frac{33}{5}-\frac{4}{3}x=0
Subtract 10 from 43 to get 33.
-\frac{17}{15}x+\frac{33}{5}=0
Combine 0.2x and -\frac{4}{3}x to get -\frac{17}{15}x.
-\frac{17}{15}x=-\frac{33}{5}
Subtract \frac{33}{5} from both sides. Anything subtracted from zero gives its negation.
x=\frac{-\frac{33}{5}}{-\frac{17}{15}}
Divide both sides by -\frac{17}{15}.
x=\frac{-33}{5\left(-\frac{17}{15}\right)}
Express \frac{-\frac{33}{5}}{-\frac{17}{15}} as a single fraction.
x=\frac{-33}{-\frac{17}{3}}
Multiply 5 and -\frac{17}{15} to get -\frac{17}{3}.
