2\times \frac{0.4x-9}{0.5}-\left(x-5\right)=2\times \frac{0.03+0.02x}{0.03}
Multiply both sides of the equation by 2.
2\times \frac{0.4x-9}{0.5}-x-\left(-5\right)=2\times \frac{0.03+0.02x}{0.03}
To find the opposite of x-5, find the opposite of each term.
2\times \frac{0.4x-9}{0.5}-x+5=2\times \frac{0.03+0.02x}{0.03}
The opposite of -5 is 5.
2\left(\frac{0.4x}{0.5}+\frac{-9}{0.5}\right)-x+5=2\times \frac{0.03+0.02x}{0.03}
Divide each term of 0.4x-9 by 0.5 to get \frac{0.4x}{0.5}+\frac{-9}{0.5}.
2\left(0.8x+\frac{-9}{0.5}\right)-x+5=2\times \frac{0.03+0.02x}{0.03}
Divide 0.4x by 0.5 to get 0.8x.
2\left(0.8x+\frac{-90}{5}\right)-x+5=2\times \frac{0.03+0.02x}{0.03}
Expand \frac{-9}{0.5} by multiplying both numerator and the denominator by 10.
2\left(0.8x-18\right)-x+5=2\times \frac{0.03+0.02x}{0.03}
Divide -90 by 5 to get -18.
1.6x-36-x+5=2\times \frac{0.03+0.02x}{0.03}
Use the distributive property to multiply 2 by 0.8x-18.
0.6x-36+5=2\times \frac{0.03+0.02x}{0.03}
Combine 1.6x and -x to get 0.6x.
0.6x-31=2\times \frac{0.03+0.02x}{0.03}
Add -36 and 5 to get -31.
0.6x-31=2\left(\frac{0.03}{0.03}+\frac{0.02x}{0.03}\right)
Divide each term of 0.03+0.02x by 0.03 to get \frac{0.03}{0.03}+\frac{0.02x}{0.03}.
0.6x-31=2\left(1+\frac{0.02x}{0.03}\right)
Divide 0.03 by 0.03 to get 1.
0.6x-31=2\left(1+\frac{2}{3}x\right)
Divide 0.02x by 0.03 to get \frac{2}{3}x.
0.6x-31=2+\frac{4}{3}x
Use the distributive property to multiply 2 by 1+\frac{2}{3}x.
0.6x-31-\frac{4}{3}x=2
Subtract \frac{4}{3}x from both sides.
-\frac{11}{15}x-31=2
Combine 0.6x and -\frac{4}{3}x to get -\frac{11}{15}x.
-\frac{11}{15}x=2+31
Add 31 to both sides.
-\frac{11}{15}x=33
Add 2 and 31 to get 33.
x=\frac{33}{-\frac{11}{15}}
Divide both sides by -\frac{11}{15}.
