Question Find the solution to the following system by substitution. 5x+ y=30 y=5x A.(0,30) B.(6,30) C.(3,15) D.(6,0)

Answer: c Step-by-step explanation: plug in 5x for y to get 5x+5x=30. combine to get 10x=30. divide by 10 on both sides to get x=3. sub that in for x. we know that y=5x, so if we plug in 3 for x, you get 5*3=y. 5*3 is 15, so y=15. the solution is (3,15) which is c Reply

The answer to your question is C

Answer:Step-by-step explanation:. sub that in for x. we know that y=5x, so if we plug in 3 for x, you get 5*3=y. 5*3 is 15, sox=3y=15. the solution is (3,15) which is c
