Respuesta :
5x+10y = 800
replace y by 50: 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
replace x=60 and y=50
so; 5(60) +10(50) =800
300 + 500 = 800
800 = 800
replace y by 50: 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
replace x=60 and y=50
so; 5(60) +10(50) =800
300 + 500 = 800
800 = 800
Answer:
60 in total
Step-by-step explanation:
proof: 5x+10y = 800
replace x=60 and y=50
so; 5(60) +10(50) =800
300 + 500 = 800
800 = 800
