Answer:
The values of x = y = z = 1
Step-by-step explanation:
Given three linear equation as ,
x + 2y + z = 4 .......a
4y - 3z = 1 .......b
y + 5z = 6 ........c
Now solve eq a and b first
4y - 3z = 1 × 5
y + 5z = 6 × 3
Or, 20y - 15z = 5
3 y + 15z = 18
so ,(20y - 15) + (3y +15 ) = 5 +18
or, 23 y = 23
∴ y = 1
Now put this y value in eq c
so , 1 + 5z = 6 ,
Or, 5z = 6-1 =5
∴ z = 1
Again put this y and z value in eq a
so, x + 2(1) + (1) = 4
Or, x = 4 -3
∴ x = 1
Hence from the above solutions , the value of x = y =z = 1 Answer

Collect like terms


Rewrite:

Substitute
in 


Divide both sides by 2

Recall that: 


Let i = sqrt(-1) which is the conventional notation to set up an imaginary number
The idea is to break up the radicand, aka stuff under the square root, to simplify
sqrt(-8) = sqrt(-1*4*2)
sqrt(-8) = sqrt(-1)*sqrt(4)*sqrt(2)
sqrt(-8) = i*2*sqrt(2)
sqrt(-8) = 2i*sqrt(2)
