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