## justingresham14 2 years ago Solve: 2(x + 1) = −8 5 −3 −5 −4.5

Ok, We would first want to distribute on the left side of the equation. Could you do that for me?

2. NobodySpecial

2(-5+1) = -8 x = -5

@NobodySpecial We don't just give answers, nor do we not show our work.

2(x + 1) = −8 or, 2x + 2 = -8 or, 2x = -10 or, x = -5........................................Ans.

5. NobodySpecial

2(-5 + 1) = -8 is my work....

6. austinL

That isn't work, that is using a guess and check technique. @goformit100 used an algebraic method that I had planned on guiding the asker through.

7. NobodySpecial

Guess and check works fine with multiple choice.

8. austinL

One last thing before I go, Guess and check may work fine for multiple choice. However, to apply this to later problems that do not offer choices for answers; you need to know how to solve the problems algebraically.

9. NobodySpecial

@austinL I agree completely.

I am Sorry Sir. Please Excuse me for my deeds :'(

@goformit100 You aren't the one that I was referring to...
