Question

Solve this system of equations. Write the answer as an ordered pair.
y = x
2x + 5y = 28......and.....Solve this system of equations. Write your answer as an ordered pair.
y + 6 = x
2x + 2y = 0

Answer 1

for the first one i got (22,0)....and the second (0,4)

Answer 2

and it said they were both wrong

Answer 3

brother here y=x now put it in equation 2
2x +5x =28
7x=28
x=4
now y=x
so y=4
(x,y) = ( 4,4)

Answer 4

THAT WAS MY FIRST ANSWER AND I WAS LIKE, NOPE THAT DOESNT SEEM RIGHT!!!!!!

Answer 5

y=x-6
put it in equation 2
2x +2(x-6) =0
2x + 2x -12 =0
4x =12
x=3
now put x=3 into y= x-6
y=3-6
y=-3
so (x,y) = (3,-3)

Answer 6

both are correct @kyle_bradley

Answer 7

ok, thank you so much. the first one i had right but deleted it and the second one sounds good

Answer 8

in the first y=x therefore it is correct

Answer 9
