Solve for x, y, and z:

3x - y + z = -3
-2x + y - 2z = 8
-4xl + 3y - z = 6

The value of x=1; y=2; z=-4

Solution:

As given in the problem,  

-----(i)

----- (ii)

So From (i) and (ii) we get,

-----------(iii)

Now,

  (// substituting value of y from (i))

(//substituting value of z from (iii))

So from (iii) we get,

And From (i) we get,

Therefore, the value of x is 1; y is 2 and z is -4.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
