Solve the system of equations by the substitution method.
12x + 6y= 15
- 2x=y+4

12x + 6y = 15

-2x = y + 4 >   0 = 2x + y + 4  >  -y = 2x + 4 > y= -2x -4

12x + 6 ( -2x - 4 ) = 15

12x -12x - 24 = 15

-24 = 15

No solutions

Step-by-step explanation:

-24 does not equal 15 so this problem has no solutions.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
