Question

3x-2y=10 3x-2y=14 solve using substitution or elimination. What's the answer?

Answer 1

I hope this helps you



-3x+2y= -10


3x-2y=14



-3x+2y+3x-2y= -10+14


0+0= 6


0=6 false it's not inconsistent

Answer 2

Let's do elimination since the left sides have the same coefficients.

3x - 2y = 10
3x - 2y = 14

To eliminate, subtract the second equation from the first by multiplying the equation by -1. 

3x - 2y = 10
-3x +2y = -14
------------------
0 + 0 = 10 - 14
0 = -4

Hey that's not true! 0 does not equal -4, which means there is no solution to the two equations.
You can confirm this by graphing. The equations do not intersect and therefore there will be no solution.
