Answer:
x = 3; y = -2; z = 1.
Step-by-step explanation:
-x + 2y + 4z = -3
x – 2y - 3z = 4
(-x + x) + (2y - 2y) + (4z - 3z) = (-3 + 4)
0 + 0 + z = 1
z = 1
x - 2y - 3(1) = 4
x - 2y - 3 = 4
x - 2y = 7
x = 2y + 7
2(2y + 7) + y - (1) = 3
4y + 14 + y - 1 = 3
5y + 13 = 3
5y = -10
y = -2
x = 2(-2) + 7
x = -4 + 7
x = 3
So, your answer is (3, -2, 1).
Hope this helps!
x=3, y=-2, z=1

Right Triangles and the Pythagorean Theorem
1.The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
2.The side opposite the right angle is called the hypotenuse (side c in the figure).
