Step-by-step explanation:
3 rolls of steamer + 2 packages of balloons = $10 -------------- (1)
2 rolls of steamer + 1 package of balloons = $6.25 --------- (2)
(2) x 2:
4 rolls of steamer + 2 package of balloons = $12.50 --------- (2a)
(2a) - (1):
1 roll of steamer = $2.50 ----------- Sub into (1)
3 ($2.50) + 2 packages of balloons = $10
$7.50 + 2 packages of balloons = $10
2 packages of balloons = $10 - $7.50
2 packages of balloons = $2.50
1 packages of balloons = $1.25
1 packages of balloons = $1.25
1 roll of steamer = $2.50
1 packages of balloons + 1 roll of steamer = $1.25 + $2.50 = $3.75
