<PRE><B>Question 942243</B>
H=no of hamburgers C=no of cheeseburgers
C=H-59
H+C=491 substitute above for C and solve for H
H+(H-59)=491
2H-59=491 Add 59 to each side
2H-59+59=491+59
2H=550 Divide both sides by 2
2H/2=550/2
H=275 Number of hamburgers = 275
C=275-59=216 Number of cheeseburgers=216
CHECK:
H+C=491
275+216=491
491=491</PRE>
