Answer:
(2,4) is a solution to this system of equations
Step-by-step explanation:
Given system of equation are


To find the solution of the given system of equations
To Check that (2,4) is a solution to this system or not
Solving equations (1) and (2)
From equation (1) and y=2x
Now substitute y=2x is equation (2)






10-5x=0
-5x=-10

Substitute x=2 in equation (1)
y=2x
y=2(2)
Therefore y=4
Therefore the solution is (2,4)
Therefore (2,4) is a solution to the system of equations.

I suspect you may have slipped up as you copied the question. Exactly as you wrote it, it has a single zero, at x= 2 .
I think it would be c if it were a greater rate I don't know if i am right I'll check back with you guys on the answer
500 dots: this is because 1 minute is 5 dots. So, 5×100=500!
