Answer:
x= 1
Step-by-step explanation:
The value of y = -5x
Plug it in the equation of y + 4x = -1
So it becomes, -5x + 4x = -1
Combine like terms which are -5x and 4x which equals to -x
Eliminate the negative sign because x cannot be negative. Apply that to -1. It becomes 1.

Answer:
See below
Step-by-step explanation:
The three angles inside of the triangle sum to 180
11x + 4 + 3x + 78 = 180
14x +82 =180
x = 7
then B = 11x + 4 = 11(7) + 4 = 81 degrees
C = 3x = 21 degrees
