Iwill give a lot of points and brainliest


1) what are the different methods for solving a system of equations? 2)what are the different types of solutions you can get when solving a system of equations? 3) how can graphing methods solve a system of equations?

Hello there!

First of all, I like your profile picture!

1) There's a lot of different methods for solving a system of equation. But here are my three favorite.

2) When solving a system of equations, you can get;

3) The graphing method help solving a system of equation by knowing that the solution to a system of equations is the point of intersection of the two lines.

I hope this answer helps. As always, it is my pleasure helping student like you!

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
