Question

solve the following linear equations by substituting: -4x+2y=-12 and 8x+4y=24

Answer 1

4y=-8x+24
y=-2x+6
Now plug that into y in following equation
-4x+2y=-12

Answer 2

you can find x find setting
y=2x-6 =-2x+6

Answer 3

If you're finding the solution there's much more to do

Answer 4

The solution to 2 crossing lines will be a point, (x,y)

Answer 5

trying to find out if its consistent or inconsistent or dependant

Answer 6

2x-6=-2x+6
4x-12
4x=12
x=3

Answer 7

Now plug that into one of the equation to find y

Answer 8

Inconsistent means no solution. Consistent means 1 solution. Dependant means infinite solutions (same line).
