?
​

Answer 1

Answer:X=1

Step-by-step explanation:

Answer 2

SOLUTION

GIVEN

Consider the following linear equations

4x + 3y - 4z = 3

x - y + z = 1

2x - y = 1

TO DETERMINE

The value of x

EVALUATION

Here the given system of linear equations are

4x + 3y - 4z = 3 - - - - - (1)

x - y + z = 1 - - - - - - - (2)

2x - y = 1 - - - - - - (3)

Multiplying Equation 2 by 4 we get

4x - 4y + 4z = 4 - - - - - - - (4)

Equation 1 + Equation 4 gives

8x - y = 7 - - - - - - (5)

Now Equation 5 - Equation 3 gives

6x = 6

$\sf{ \implies \: x = 1}$

FINAL ANSWER

Hence the required value of x = 1
