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
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.
