Thank you for the opportunity to help you with your question!

---------------------------------------------------------------------------------------

4x - 5y = 5 ----(1)

-0.08x + 0.10y = 0.10 ---(2)


Multiply equation (2) by 50

50*(-0.08x) + 50*0.10y = 50*0.10

-4x + 5y = 5 ---(3)


Add equations (1) and (3)

4x - 5y + (-4x + 5y) = 5 + 5

4x - 5y - 4x + 5y = 10

0 = 10

which is not possible.


So, the system of equations has no solution.


ANSWER:  no solutions
