Question 347824
You need a clearer idea of what "solve" means
There is no way to solve 1 equation with 2

The number of unknowns has to equal the
number of equations in order to solve.
I can plot this line, but you need some
other line, and their intersection is the solution
{{{ graph( 400, 400, -10, 10, -10, 10, 2x - 5 ) }}}
