What is the solution to the following system of equations?
X - 3y = 5
2x + y = 10
(5,0)
(0,5)
(7,0)
(0,7)

Answer 1

( 5, 0 )

Explanation:

x - 3y = 5

2x + y = 10 multiply by 3 to eliminate y and solve for x

x - 3y = 5

6x + 3y = 30 then add

7x = 35

simplify:

x = 35 / 7

x = 5

substitute x = 5 back into the eq.2

2x + y = 10

2(5) + y = 10

y = 10 - 10

y = 0

therefore the answer is ( 5, 0 )

Answer 2

Option 1 is the correct answer

(5,0)
