4x-22,5+12,5x=6
Use the distributive property to multiply -5 by 4,5-2,5x.
16,5x-22,5=6
Combine 4x and 12,5x to get 16,5x.
16,5x=6+22,5
Add 22,5 to both sides.
16,5x=28,5
Add 6 and 22,5 to get 28,5.
x=\frac{28,5}{16,5}
Divide both sides by 16,5.
x=\frac{285}{165}
Expand \frac{28,5}{16,5} by multiplying both numerator and the denominator by 10.
x=\frac{19}{11}
Reduce the fraction \frac{285}{165} to lowest terms by extracting and canceling out 15.
