0.3x-3=0.1x+3
Use the distributive property to multiply 0.1 by x+30.
0.3x-3-0.1x=3
Subtract 0.1x from both sides.
0.2x-3=3
Combine 0.3x and -0.1x to get 0.2x.
0.2x=3+3
Add 3 to both sides.
0.2x=6
Add 3 and 3 to get 6.
x=\frac{6}{0.2}
Divide both sides by 0.2.
x=\frac{60}{2}
Expand \frac{6}{0.2} by multiplying both numerator and the denominator by 10.
x=30
Divide 60 by 2 to get 30.
