Question

Which ordered pair is a solution of the equation? 3 x + 3 y = − x + 5 y 3x+3y=−x+5y
option A) only (1,2) B) only (2,4) C) both or D) neither

Answer 1

Answer:

OPTION C=BOTH

Step-by-step explanation:

3x+3y=−x+5y

Using (1,2)

3(1)+3(2)=-(1)+5(2)

3+6=-1+10

9=9

using (2,4)

3(2)+3(4)=-(2)+5(4)

6+12=-2+20

18=18

so both are solution
