Add the last two equations to eliminate <em>x</em> :
(<em>x</em> - 2<em>y</em> - 3<em>z</em>) + (- <em>x</em> + <em>y</em> + 2<em>z</em>) = 0 + 3
- <em>y</em> - <em>z</em> = 3
<em>y</em> + <em>z</em> = -3
Subtract this from the first equation to eliminate <em>z</em>, then solve for <em>y</em> :
(2<em>y</em> + <em>z</em>) - (<em>y</em> + <em>z</em>) = -8 - (-3)
<em>y</em> = -5
Plug this into the first equation to solve for <em>z</em> :
2(-5) + <em>z</em> = -8
<em>z</em> = 2
Plug both of these into either the second or third equations to solve for <em>x</em> :
<em>x</em> - 2(-5) - 3(2) = 0
<em>x</em> = -4
Answer:
1. 601/1000
2. 60.1/100
3. 6.01/100
Step-by-step explanation: To get 60.1% to a fraction, divide by 100. You will get 60.1/100, which is the answer with the denominator of 100. For the denominator of 1000, multiply the numerator and denominator by 10.
60.1 x 10 = 601
100 x 10 = 1000
The fraction for the denominator with 1000 is 601/1000. For the denominator of 10, divide the numerator and denominator by 10.
60.1/10 = 6.01
100/10 = 10
The fraction for the denominator with 10 is 6.01/10.

Answer:
The solution of given equation is ( - 1 + 2 i ) , ( - 1 - 2 i )
Step-by-step explanation:
Given equation as :
3 x² + 6 x +15 = 0
The value of x fro the quadratic equation a x² + b x + c = 0 is obtained as
x = 
So , from given eq , the value of x is now obtain as
x = 
Or, x = 
Or, x = 
∴ x = ( - 1 + 2 i ) , ( - 1 - 2 i )
Hence The solution of given equation is ( - 1 + 2 i ) , ( - 1 - 2 i ) Answer
