Question

x = 3y - 6
2x - 4y = 8
Solve the system of equations using substitution.

Answer 1

okay so x is 3y-6
so plug it into the second equation
so 2(3y-6)-4y=8
then solve for y

Answer 2

@rebeccaxhawaii is y 2x-4y or..

Answer 3

2(3y-6)-4y=8 solve for y

Answer 4

i distributed and got 6y - 16 - 4y =8

Answer 5

how did you get 16?

Answer 6

6 x 2=12

Answer 7

i told you i distributed

Answer 8

so it should be `6y - 12 - 4y =8 ` instead of `6y - 16 - 4y =8 ` (I changed the -16 to -12)

Answer 9

what comes next after `6y - 12 - 4y =8` ?

Answer 10

umm do i solve it like aregular equation....subtract 12 from both sides

Answer 11

what is 6y-4y equal to?

Answer 12

2y

Answer 13

so we now have 2y-12 = 8

now add 12 to both sides to undo the -12

Answer 14

y=10

Answer 15

y = 10 is correct

Answer 16

then you'll go back to `x = 3y - 6` and plug in y = 10 to find x

Answer 17

x=24

Answer 18

correct

Answer 19

4x + 3y = 6
-4x + 2y = 14
