Question

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

Answer 1

Answer:

-4=x

Step-by-step 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

Answer:

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

Step-by-step 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

$\dashrightarrow{ \sf{ \frac{5x}{5} = \frac{ - 20}{5} }}$

Calculate

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

Hope I helped!
