Question 990978
.
{{{system(y=-2x+3,
4x+2y=12)}}}.


Simply substitute the expression for &nbsp;<B>y</B>&nbsp; from the first equation to the second one. &nbsp;You will get


4x + 2*(-2x+3) = 12.


Simplify it:


4x - 4x + 6 = 12.


6 = 12. 


Could it be so? &nbsp;&nbsp;-No.


It means that your system has no solution.


Geometrically the original equations represent two parallel straight lines in a coordinate plane that have no intersection - have no common point.
