Question

I need help solving this equation:
-(1+7x) -6(-7-x)=36

Answer 1

Multiply in first
6(-7-x) = ...

Answer 2

-(1+7x) - 42- 6x = 36
-1- 7x - 42 - 6x = 32
-1 - 13x - 42 = 32
-43 - 13x = 32
- 13x = 75
-x = 5.76923
okay what did i do wrong....

Answer 3

-(1+7x) +42 +6x = 36

Answer 4

Your sign is wrong right at the first step of distribution !

Answer 5

Any more questions?

Answer 6

can you distribute it for me? I dont see what i'm doing wrong accept i go to check my answer and it doesnt work

Answer 7

-1-7x +42 +6x = 36
-x = 36 - 42 + 1 = -5
=> x = 5

Answer 8

I still don't get it, how does that work and what's up with the => x = 5 at the end?

Answer 9

It might be helpful to view
-(1+7x) -6(-7-x)=36
as
-(1+7x) + -6(-7-x)=36

Answer 10

I told you that your signs is wrong at first line:
-(1+7x) - 42- 6x = 36 ( wrong)
Compare with:
-1-7x +42 +6x = 36

Answer 11

-(1+7x) + -6(-7-x) = 36
-1+ - 7x + 42 + 6x = 36
41 + - x = 36
-x = -5
x = 5
I got this answer already but when I tested it, it didn't work.

Answer 12

5 is correct

Answer 13

-(1+7(5)) + -6(-7-(5)) = 36
-(1+35) + 42 + 30 = 36
-(1 + 35) + 72 = 36
-1 + -35 + 72 = 36
-36 + 72 = 36

oh I tested it wrong. I see now, okay, thank you both so much!
