Solve for (x, y, z), if there is a solution to the given system of linear equations:
x - 3y - 2z = -3
3x + 2y - z = 12
-x - y + 4z = 3

x=4, y=1, z=2

Step-by-step explanation:

System Of 3 Linear Equations

When 3 variables x,y,z are related through 3 independent linear equations, we could find a combination of them which makes the 3 equations become identities. That can be achieved in a very high number of methods.

Let's solve the system of equations shown in the question

Let's add the first and third equation to eliminate x:

Solving for z

Now we multiply the third equation by 3 and sum it to the second

We know that x=2y, so

This gives us

From the very first equation we solve for x

Replacing y=1, z=2, we get

The solution is

x=4, y=1, z=2

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
