Question

Solve using substitution:
y=-x^2+3
Y=3x-7

Answer 1

Can anyone help me

Answer 2

okie dokie.
We know y=3x-7
So since y=x^2+3 then 3x-7=x^2+3
Then make a quadratic equation
x^2-3x+10=0

Answer 3

Then use quadratic equation to solve for x, Plugin BOTH x's in BOTH formulas to check if both X value is correct, if one of them or both do not work then negate them
