Answer 1

Step-by-step explanation:

Explanation:

We will solve the Problem using Method of Substitution :

From the

2

n

d

eqn.,

x

=

2

y

−

3

z

+

1

...

(

)

Substituting in the

1

s

t

e

q

n

.

,

2

(

2

y

−

3

z

+

1

)

−

y

+

3

z

=

2

⇒

3

y

−

3

z

=

0

⇒

y

=

z
