Answer:

x = -4/5

Step-by-step explanation:

Original equation: -(x+4)-3x=x

Remember distributive property allows us to get rid of the parenthesis by bringing a multiplication from outside to inside a parenthesis.

-(x+4) = -x-4

= -x-4-3x=x

Now we combine like terms in this case we have (-x) and (-3x)

= -4x-4=x

Subtract x from both sides

= -4x-4=x

-x -x

----------------

-5x-4=0

Add 4 to both sides

-5x-4=0

+4 +4

---------------

-5x=4

Our final step is to divide both sides by -5

-5x=4

---- ----

-5 -5

x = -4/5

Hope this helps!!!

R_1 = \boxed{3\sqrt{\frac{6}{5}} }$

Answer:

Line BD is Congruent to Line BD due to the Reflexive property. Angle Bad is congruent to angle BCD because of the third angle theorem therefore triangle ABD is congruent to triangle CBD because all angles and sides are congruent

I don't know if that will satisfy your teacher because some prefer different things but that leaves no ground to be inferred and explains everything word for word.
