The linear equation shown below expresses the revenue of a café based on the number of children and adults who ate there last tuesday. 10x + 15y = 180 x = number of children y = number of adults if 10 adults ate at the café that day, how many children also ate there?

3 children ate there.

Step-by-step explanation:

Given linear equation that shows the  revenue of a café based on the number of children and adults who ate,

10x + 15y = 180  

Where, x represents number of children,

y represents number of adults,

If y = 10,

Then from the above equation,

10x + 15(10) = 180

10x = 180 - 150 = 30

x = 3

Hence, 3 children ate there.

it is x=-4
