Answer:
x= [tex]\frac{\sqrt{42} }{3}[/tex]
y= -9
Step-by-step explanation:
To solve this problem you need to use substitution. You substitute [tex]y=3x^{2} +5[/tex] into y in [tex]-2x^{2} +y=-5[/tex] and solve for x. Then once you have found the value of x you plug that number into [tex]y=3x^{2} +5[/tex] to find the value of y.
