The middle angles of a rhombus are 90 degrees which means the other two angles of the triangle must total 90 degrees.
(8x +7) + (3x + 6) = 90
11x + 13 = 90
11x = 77
x = 7

Solve the system of equations:<br> y = x-4<br> -2x + y = 18
Pie

Answer:

x = 7.3

Step-by-step explanation:

-2x + x-4 = 18

First, Combine Like Terms

-3x + (-4) = 18

Then, do Inverse Operations

-3x + -4 = 18

       + 4   +4

Cancel out the -4 +4 because it will equal zero and won't matter to the equation

-3x = 22

Do Inverse Operations again. In this case, you will divide.

-3x = 22

-3x/-3 = 22/-3

Cancel out the -3x/-3

22/-3 = x

7.3 = x
