Answer:
the answer is e=mc^2 I think
Solve first equation for y:
5x+y=10
y=10-5x. Plug this equation into second equation
-x-(10-5x)=-2
-x-10+5x=-2
4x=8
x=2 (plug x into first equation)
5(2)+y=10
y=0
I too also need this answer.
Answer:
4 people will be expected to win the prize
Step-by-step explanation:
Out of 15 people, 5 won a prize

Answer:
5x - 2 = 3x = 14
8x -2 = 14
8x = 14 + 2
8x = 16
x = 2
