Y=2x x=-y+6
what does it equal to

i believe the answer is the polygon, heptagon.

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
