Graphing Linear Equation Help (Medal)


I have graphed a linear equation where it is obvious the lines intersect, but not on an exact point. How do I find the solution?

Answer 1

example

Answer 2

we have these two equations

y = 3x
x+2y = 4

Answer 3

Start with the equation x + 2y = 4 and replace y with 3x (since y = 3x) to get...


x+2y = 4

x + 2(3x) = 4 ... replace y with 3x

x + 6x = 4

do you know how to solve from here?
