Question

MEDALS WILL BE GIVEN FOR THIS ONE EASY QUESTION 9) Solve the system using substitution.
x = 2y + 6
x + y = 12

Answer 1

2y+6 + y = 12

Answer 2

first we have to set the equation to look like y = mx +b

Answer 3

the equations***

Answer 4

@DSS show your work ?

Answer 5

I did. I substituted 2y +6 in for x in the 2nd equation.

Answer 6

thank youuuu ( :

Answer 7

What did you get

Answer 8

x+ 2 ?

Answer 9

2y+6 + y = 12
3y + 6 = 12
3y = 6
y = 2

Answer 10

tht is right bettylove

Answer 11

That is not right.

Answer 12

yes it is

Answer 13

@DSS what about this Solve the system using elimination.
3x – 9y = 18
x + 2y = 1

Answer 14

No. y = 2 and x = 10...Please check your work memek12

Answer 15

2y+6 + y = 12 3y + 6 = 12 3y = 6 y = 2

Answer 16

3x – 9y = 18 3x -9y = 18 3x -9y = 18
x + 2y = 1 -3(x+2y=1) -3x-6y = -3
-15y = 15
y = -1

To find x, substitute -1 in for y and solve.
