Question

Help with solving simulatenous equations with 1 quadratic . question attached

Answer 1

Answer:

x = 1/2, y = 17/2

x = -3, y = 12

Answer 2

Answer:

x= -3, y=12

x=1/2, y=8 1/2

Step-by-step explanation:

y = 9-x

y= 2x²+4x+6

• 9-x= 2x²+4x+6
• 2x²+5x-3=0

solving, we get

• x= -3 and x= 1/2

then

• for x= -3, y= 9+3= 12

• for x=1/2, y= 9-1/2= 8 1/2
