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

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!

Best regards! :D
