Answer:
(5,-6) is a solution
Step-by-step explanation:
Given


Required
Tell whether (5,-6) is a solution
In (5,-6): x = 5 and y = -6.
Substitute these values in the given equations
becomes



becomes



Because both solutions are true, then (5,-6) is a solution
The numerical form of this worded expression is:
10(1/2n + 6)=8
Answer:
2km/m
Step-by-step explanation:
