Question

-x+7= -6x-13 how do you solve it

Answer 1

-4=x

Explanation:

Okay, let's do this step-by-step for the best results!

We need to make sure that common variables can be put together first. If you did not know this, look at PEMDAS.

-x+7=-6x-13

We need to add -x and -6x together. If we do that then you would get,

7=-5x-13

Let's add 13 to 7 now.

20=-5x

Lets divide -5 with 20.

-4=x

I hope this helped!

Answer 2

`\boxed{ \bold{ \huge{ \boxed{ \sf{x = - 4}}}}}`

Explanation:

`\sf{ - x + 7 = - 6x - 13}`

Move 6x to left hand side and change it's sign

`\dashrightarrow{ \sf{ - x + 6x + 7 = - 13}}`

Move 7 to right hand side and change it's sign

`\dashrightarrow{ \sf{ - x + 6x = - 13 - 7}}`

Collect like terms

`\dashrightarrow{ \sf{ 5x = - 13 - 7}}`

Calculate

`\dashrightarrow{ \sf{5x = - 20}}`

Divide both sides by 5

`\dashrightarrow{ \sf{ (5x)/(5) = ( - 20)/(5) }}`

Calculate

`\dashrightarrow{ \sf{x = - 4}}`

Hope I helped!
