Question 1069198
Dividing both sides of the second equation by 2 gives {{{(4x+10y)/2=1/2}}}


{{{2x+5y=1/2}}}


Now, your system of equations shown more simply is  {{{system(2x+5y=4,2x+5y=1/2)}}}
Their slopes are equal; they represent parallel lines and will not intersect, so this system has no solution.
