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

leave the y by itself
Venomblast
  • Venomblast
well you can solve for y. iof you divide -2 on both side, y should equal -2

The answer I got was C

no worries dear :) @iheartfood by the way, I <3 food too!!!
Venomblast
  • Venomblast
so 4(2) + 5(-4(2) - 2) = -18 8+5(-8-2)=-18 8+5(-10)=-18 8-50=-18 -42=-18 FALSE
Venomblast
  • Venomblast
now all you have to do is plug it in for each. dont worry i will help you

you did? i didnt get it i think. imaybe i just miss it
anonymous
  • anonymous
It's fine love
Venomblast
  • Venomblast
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

anonymous
  • anonymous
you can email me if you want some time :) i have a lot to offer. part of what makes me upset about getting on here, is that people know me for my lack of understanding in math, and that's the only judgement they can make about me, when i'm very intelligent in other aspects
Venomblast
  • Venomblast
do people judge you at this site?
anonymous
  • anonymous
I've gotten very negative feedback a few times

Venomblast
  • Venomblast
really.. i thought this was an peaceful site.
anonymous
  • anonymous
another time this one lady gave me the hardest time when all I was doing was learning. i could easily say "f you" to learning math, but I try to at least get my answers checked and look for explanations if i'm incorrect
Venomblast
  • Venomblast
yea dont bother with people that has no patience. not worth it, i can make you learn math. i love to help
anonymous
  • anonymous

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)
Venomblast
  • Venomblast
that one whole equation?
Venomblast
  • Venomblast
let me guess, the 1st column is x the second is y and the last is z?
anonymous
  • anonymous
yes
anonymous
  • anonymous
I think you break it down into two, so you separate it
Venomblast
  • Venomblast
lol i got this
anonymous
  • anonymous
into three rather***
anonymous
  • anonymous
I have faith in YOU;)
Venomblast
  • Venomblast
is that a 2x or .2x?
anonymous
  • anonymous
huh?
Venomblast
  • Venomblast
on the beginning of the question
anonymous
  • anonymous
No period in the beginning, my error 2x + 3y - z = 13x + y + 2z = 12x + 2y - 3z = -5
Venomblast
  • Venomblast
what math course are you taking?
