I don’t think you pick an answer you just put all of those formulas and solutions into your calculator and that will give you what you need to move onto the next question/ step
Hello : the system is :
<span> y= -2x+4 ...(1)
y= x² +4x+13....(2)
x²+4x+13 = -2x+4
x²+6x+9=0
(x+3)² =0
x+3=0
x= -3
subsct in (1) : y=-2(-3)+4 =10</span>
