Ответ:
y = 2 + 3x
Nick:
y = 6 + x
Where 'y' is the total cost, and 'x' represents the number of hours.
Solve using substitution, we can substitute 2 + 3x for 'y' in the 2nd equation.
y = 6 + x
2 + 3x = 6 + x
Subtract 2 to both sides:
3x = 4 + x
Subtract 'x' to both sides:
2x = 4
Divide 2 to both sides:
x = 2
Now we can plug this into any of the two equations to get our 'y' value.
y = 2 + 3x
y = 2 + 3(2)
y = 2 + 6
y = 8
So our full solution is (2, 8).
Which means they both bowled for 2 hours, and spent €8.
