Question

x - y = 0, 6x+5y=-22 the lines intersect at?

Answer 1

To find the intersection between the two lines we can do this :
From the equation of the 1st line we have :
\[\Large y=x\]
So, when we replace it in the 2nd equation :
\[\Large 6x+5x=-22\]
So :
\[\Large 11x=-22\]
So :
\[\Large x=\frac{-22}{11}=-2\]
So the two line intersect in the point (-2,-2-
