Mathematics
1 answer:
Vinil7 [7]3 years ago
7 0

Step-by-step explanation:

-5x+8y=-4

6x-8y=-12   8y and 8x cancel out

         x=-16

To solve for y, substitute x=-16 back into the first equation

-5(-16)+8y=-4

    80+8y=-4

          8y=-84

            y=-10.5

I need to find the value of X
nirvana33 [79]

Answer:

17.7

Step-by-step explanation:

This figure is a pentagon - a shape with 5 sides. In a pentagon, the figure's angles add to 540.

100 + 7x-4 + 3x + 23 + 9x - 6 + 90 = 540

190 +19x + 13 = 540

203 + 19x = 540

19x = 337

x = 17.7
