Question

Solve the equation x +1 − 2 = x − 7 for x and check your answer(s)

Answer 1

First combine like terms on both sides if possible.
Like terms are terms that have exactly the same variables. Terms with x are like terms and can be combined together, and terms without x are like terms and can be combined together.
In this case you have two numbers on the left side that can be combined togerther
x + 1 - 2 = x - 7
Combine the numbers on left side:
x - 1 = x - 7
Now to get all x's on left side and all numbers on right side, subtract x from both sides and add 1 to both sides
x - 1 = x - 7
-x + 1 = -x + 7
------------------
0 + 0 = 0 + 7
You get 0 = 7.
Since this is a false statement, this equation has no solution.

Answer 2

oo my you know what lol im so srry I wrote this wrong cause I was looking at what I did in my notes and what u were writing and im like?? it should be
\[\sqrt{x+1}-2=x-7\]

Answer 3

To solve this type of of equation is isolate the square root on one side, then square both sides.
