Answer:
60
Step-by-step explanation:
Substitute 50 for y in the formula
5x+10y=800
5x+10*50=800
5x+500=800
5x=800-500
5x=300
x=300/5
x=60
Answer:
60
Step-by-step explanation:
5x+10y = 800
5x+10(50) = 800
5x+500 = 800
5x = 800-500
5x = 300
x = 300/5
x = 60
60 small vehicles were washed in total.
proof: 5x+10y = 800
5(60) +10(50) =800
300 + 500 = 800
800 = 800
