y = 3x+5

y= 4x^2+x      since we want to find where the equations are equal...just equate them

 

4x^2 +x = 3x+5     and rearrange

4x^2-2x-5 = 0          now use quadratic formula to find x = 1.39564     x= −0.895644

     then plug those values of 'x' into one of the equations  (3x+5 would be the easiest)  to find the corresponding 'y' values.......
