Question

I'll tell you a secret if you help me? :)))))


If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to y from the first equation is substituted into the second equation.8x

- 2y = 4
4x + 5y = -18

Answer options:

4x + 5(-4x - 2) = -18

4x + 5(4x - 2) = -18

4(-4x - 2) + 5y = -18

4(4x - 2) + 5y = -18

Answer 1

bet

Answer 2

leave the y by itself

Answer 3

well you can solve for y. iof you divide -2 on both side, y should equal -2

Answer 4

now plug -2 for y

Answer 5

I have that :)

Answer 6

help me!!!!!!!!!!!:(((((((((((((

Answer 7

ok ok lol

Answer 8

if you plug in for y. x should equal 2

Answer 9

The answer I got was C

Answer 10

no worries dear :) @iheartfood by the way, I <3 food too!!!

Answer 11

so 4(2) + 5(-4(2) - 2) = -18
8+5(-8-2)=-18
8+5(-10)=-18
8-50=-18
-42=-18 FALSE

Answer 12

now all you have to do is plug it in for each. dont worry i will help you

Answer 13

awwwww you are sooo sweeeeet!!!!! :))))))))) @Venomblast

Answer 14

hehe thanks :)

Answer 15

Answer 22

It's fine love

Answer 23

for C 4(-4x - 2) + 5y = -18
4((-4(-2))-2)+5(-2)+=-18
4(8-2)-10=-18
4(6)-10=-18
24-10=-18 FALSE

Answer 24

1. Solve the following system of equations.2x + 3y - z = 13x + y + 2z = 12x + 2y - 3z = -5



(3, 1, 2)

(-3, 1, 2)

(3, -1, 2)

(3, 1, -2)

Answer 78

that one whole equation?

Answer 79

let me guess, the 1st column is x the second is y and the last is z?
