<span> 5x = 99 -14y
15x = -39+14y
----------------------add
20x = 60
x = 3
5(3) = 99 - 14y
15 = 99 - 14y
14y = 84
y = 6
answer
x = 3, y = 6</span>

Answer:
6
Step-by-step explanation:
The total of all the angles must be 180, since there is a straight line. We already know the 40 degree angle and the 90 degree angle, meaning that the remaining angle must be equal to 180 - 90 - 40, which is 50 degrees. Therefore, 50 = 7k + 8. 7k = 50-8 = 42, and k = 6.
