The value of x, y and z from the system of equation are -1, -8 and 5 respectively.
Data;
- -2x + 6y + 3z = -31
- -3y + 7z = 59
- 2z = 10
<h3>System of Equation</h3>
To solve this problem, we have to solve the system of equation using substitution method.
From equation (iii)
let us substitute the value of z into equation (ii)
Let's substitute the value of x and y into equation (i)
From the calculation above, the value of x, y and z are -1, -8 and 5 respectively.

Step-by-step explanation:
8 + 8 (same length)
= 16
Answer:
← SOLUTION →
OA OC
___ = _____
OB OD
→ 2x + 4
_______
9x - 21
= 2x -1
<h3>______. ( GIVEN ) </h3>
3
= 3(2x+4)
= (9x - 21) ( 2x -1)
= 6x+12
= 18x² -51 x +21
<h3>= 0</h3>
= 6x² - 19x +3.
= 0
= 6x² -18 x- x +3
<h3>= 0 </h3>
→ 6x ( x-3) - (x - 3)
<h3>= 0 </h3>
→ ( x - 3 ) (6x - 1 )
<h3>= 0 </h3>
<h3>x = 3. or x = 1 </h3>
__
6
[ but 2x-1 = {2 × 1
__ - 1 } < 0
. 6
= x= 3
or
x= 1
___
6
