6.2z+1-4z=5.5
Subtract 4z from both sides.
2.2z+1=5.5
Combine 6.2z and -4z to get 2.2z.
2.2z=5.5-1
Subtract 1 from both sides.
2.2z=4.5
Subtract 1 from 5.5 to get 4.5.
z=\frac{4.5}{2.2}
Divide both sides by 2.2.
z=\frac{45}{22}
Expand \frac{4.5}{2.2} by multiplying both numerator and the denominator by 10.
