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.
- Graphing
- Substitution (Which I preferred to use and I think it is easier).
- Elimination
2) When solving a system of equations, you can get;
- One solution
- No solution
- Infinite number of solution
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!
16x^4-81y^4 difference of perfect squares...
(4x^2-9y^2)(4x^2+9y^2) that's one of the equivalents...
(2x+3y)(2x-3y)(4x^2+9y^2) that's another one of them...
Answer:
Subtract 2x to bring it to the other side
Step-by-step explanation:
2x+5y=20
-2x. -2x
5y=-2x+20
That is so confusing the way theyou word it sometimes is like what the...what?
