Answer:
c
Step-by-step explanation:
Answer:
x=-1, y=2
Step-by-step explanation:
Plug the y=-2x into the second equation in place of the y to get 4x+10(-2x)=16
Simplify this to 4x-20x=16 then to -16x=16
Divide both side by -16 to get x=-1
Plug x=-1 into the first equation to get -2(-1)=y
Simplify to get y=2
2/5 because it is two pounds being divided up by 5 friends
no solution
subtract 7t from both sides
7t - 7t + 3 = 8 + 7t - 7t
3 = 8 is a false statement
Thus the equation has no solution
