1,6x+x+0,6x-6=3
Combine x and 0,6x to get 1,6x.
2,6x+0,6x-6=3
Combine 1,6x and x to get 2,6x.
3,2x-6=3
Combine 2,6x and 0,6x to get 3,2x.
3,2x=3+6
Add 6 to both sides.
3,2x=9
Add 3 and 6 to get 9.
x=\frac{9}{3,2}
Divide both sides by 3,2.
x=\frac{90}{32}
Expand \frac{9}{3,2} by multiplying both numerator and the denominator by 10.
x=\frac{45}{16}
Reduce the fraction \frac{90}{32} to lowest terms by extracting and canceling out 2.
