First find the x and y values because where the lines will intersect, they share the point of the intersection so they will share the x and y coordinates.
Rearrange equations
To cancel y, we must do equation 1 minus equation 2. Similarly:
So the x coordinate is 3.
The y coordinate can be found with substitution of x into one of the equations:
So where the two lines intersect is at the point (3, 7), which is the solution to the equations.
Answer:
first we get y on one side by itself.
4x+5y=5
we'll move x to the other side.
4x-4x+5y=5-4x
simplify.
5y=5-4x
now we get rid of the coefficient on y.
5y/5=(5-4x)/5
simplify.
y=5/5-4x/5
y=1-
