I drew a chart and on the side with the singers you count by 5's until u get to 30. On the dancers side of the chart you count by 6's until it lines up with 30 on the singers side.
Same question x+y=30 x is 1/5 of y x=y/5 subsitute y/5+y=30 multily both sidse by 5 y+5y=150 add 6y=150 divide both sides by 6 y=25 subsitute x=y/5 x=25/5 x=5 the numbers are 5 and 25
