A quadrilateral in total is 360 degrees.
(x = the missing length)

100 + 87 + 106 + x = 360
293 + x = 360
-293       -293
x = 67 degrees.

{x = -4y - 19
Harman [31]

Answer:

x = 9 and y = -7

Step-by-step explanation:

given:

  • x = -4y - 19
  • 2x + 2y = 4

using substitution method:

2(-4y - 19) + 2y = 4

-8y - 38 + 2y = 4

-6y = 42

y = -7

Solve for x:

x = -4(-7) - 19

x = 28 - 19

x = 9
