(please show all work this helps me understand how you got the answers, thank you!)
Given set of equations are
y=x2−3x+4 ...(1)
and x+y=4 ⇒ y=4−x ...(2)
From eq. (1) and (2)
∴ x2−3x+4=4−x
x2−2x=0
x(x−2)=0
x=0 or 2
For x=0 in eq (1) For x=2 in eq(1)
⇒ y = 4 ⇒ y = 2
∴ The solutions are (0,4) and (2,2).
