Step-by-step explanation:

Step-by-step explanation:

Given the system of equations , you can use the Elimination Method to solve it.

Multiply the first equation by -1, add both equations and then solve for the variable "x":

And finally, substitute the value of the variable "x" into any original equation and solve for the variable "y". Then:

Value of boat per year (up to 10 years)
initial value=10700
1 year= 1058
2 years= 9416
3 years= 8774
4 years= 8132
5 years= 7490
6 years= 6848
7 years= 6206
8 years= 5564
9 years= 4922
10 years= 4280
