Question

how do you find the solutions for y=x2+4x-5 and y=x2-2?

Answer 1

they give you the value of y so you would make the equations equal to each other like this
x²+4x-5=x²-2
then you have add 2 on both side

x²+4x-3=x²
make it equal to 0 by subtracting x² on both sides
4x-3=0
add 3 on both sides
4x=3
x=3/4

Answer 2

Im lost where you add 2 on both sides?

Answer 3

you are moving everything onto one side and making it equal to zero
so you do the opposite
if you got x²-2
you will subtract x² and add 2 onto both sides
