Answer 1

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.

12x - y = -4
4x - 3y = -6

4x - 3(-12x - 4) = -6
4x - 3(12x + 4) = -6
4(12x + 4) - 3y = -6
4(-12x - 4) - 3y = -6

Answer 4

these are these multiple choice answers

4x - 3(-12x - 4) = -6
4x - 3(12x + 4) = -6
4(12x + 4) - 3y = -6
4(-12x - 4) - 3y = -6

Answer 5

isolate y from 1st equation

Answer 6

*the

Answer 7

can you isolate y from 12x - y = -4
?
you can start by adding 'y' on both sides

Answer 8

ok ill try

Answer 9

12x - y = -4

12x + -4

Answer 10

umm i dont think that would be it

Answer 11

12x-y = -4

12x -y+y = -4+y

Answer 12

12x = -4+y

now add 4 on both sides similarly

Answer 13

4 + 12x = -4 + y + 4

Answer 14

yes!

so
y = 12x+4
right?

Answer 15

i think i'm gonna try to look back at some notes after this problem to better understand it
:(

Answer 16

oh i got it yah

Answer 17

yes, its easy

then plug this in 2nd equation

4x-3y =-6
4x - 3(12x + 4) = -6

Answer 18

would it be B

Answer 19

yes :)

Answer 20

thanks :)
