Question 1042659
Set the equations equal to each other.
{{{-2x+20=2x^2+3x-22}}}
{{{2x^2+5x-42=0}}}
{{{(x+6)(2x-7)=0}}}
Two solutions:
{{{x+6=0}}}
{{{x=-6}}}
and
{{{2x-7=0}}}
{{{2x=7}}}
{{{x=7/2}}}
To find the corresponding x value, use either equation,
{{{y=-2(-6)+20}}}
I leave it to you to complete the solution.
