What is the solution to the system?
X+ y - Z=0
3x - y + Z = 4
5x+z=7
+ Z = 7
(1, 1, 2)
(-1, 0, 2)
(0, 1, 4)
(-1, 2, 4)

add the 2 first equations

4x=4 so x=1

5x+z=7 so z=2

3x-y+Z=4 so y=6

so the right answer is (1,6,2)

step-by-step explanation:

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
