Answer:
(2, 6)
Step-by-step explanation:
The solution will be where the two lines intersect. From the graph, that point is (2, 6).
X = 3z - 22
z = 6
5x + 4y + 3z = 14
5 (3z - 22) + 4y + 3 (6) = 14
15z - 110 + 4y + 18 = 14
15 . 6 - 110 + 4y + 18 = 14
90 - 110 + 4y + 18 = 14
90 - 110 + 18 - 14 + 4y = 0
-16 + 4y = 0
4y = 16
y = 4
J+46=180. k+m+92=360. j+k+m=180
