We can just substitute y = 4x+1 in the second equation.

We know the value of x, substitute x in any equations to get the y-value.

The value of y is 3 and the value of x is 0.5 aka 1/2
Since you want the solution as a point then It's below here.
Check the picture below, notice those three quadrilaterals, bearing in mind that a square and rhombus both have equal sides all around.
A square plus b square = c square
(a square plus 6 square =10 square,a)
3(x)-5=x+5
3x=-5+5+x
3x=x
0=x
because 3x=x is basically would make each part into 0 which would end up the same.
