0.79hr-10hr=0
Subtract 10hr from both sides.
-9.21hr=0
Combine 0.79hr and -10hr to get -9.21hr.
\left(-\frac{921r}{100}\right)h=0
The equation is in standard form.
h=0
Divide 0 by -9.21r.
0.79hr-10hr=0
Subtract 10hr from both sides.
-9.21hr=0
Combine 0.79hr and -10hr to get -9.21hr.
\left(-\frac{921h}{100}\right)r=0
The equation is in standard form.
r=0
Divide 0 by -9.21h.
