(b) (−3, −5), because the point satisfies both equations
Step-by-step explanation:
Any solution to a system of two equations <em>must satisfy both equations</em>. The only reasonable explanation of "why" is the one associated with the answer shown above.
You have to plug in 7 for f and 8 for k making it look like -5(7)-2+8-3(8), now multiply to get the further more, -35-2+8-24, now add or subtract to get -53
