2/3x +12/3 =7
2/3x + 4 =7
2/3x=7-4
2/3x=3
x=3*3/2
x=3
10y + 70= 12y
12y-10y=70
2y=70
y=70/2=35
Answer:
Lisa bought 9 gallons of ice cream
Step-by-step explanation:
lets take "x" as the gallons of lemonade
if Lisa made purchases worth $34 that is what our equation will e equal to
ice cream:7.5 per gallon
milk: 2.5 per gallon
lemonade: 3 per gallon
since Lisa purchases 4 gallons of milk and 2 gallons of ice cream we will multiply that by the unit money for each food respectively:
7.5(2)+2.5(4)+X=34
SIMPLIFY:
15+10+x=34
15+10=25
25+x=34
25-25+x=34-25
x=9
Lisa bought 9 gallons of ice cream
hope this helps!
