Question

3. निम्न रैखिक समीकरण युग्म में x तथा y एवं z का मान ज्ञात कीजिए
X - y + 2 = 4
x + y + 2 = 2
2x + y - 32 = 0
​

Answer 1

Answer:

X=4-2+y

X=2+y.......eq(1)

Put the value of X in eq(2)

X+y+2=2

2+y+y+2=2

2y+4=2

2y=2-4

Y=-2÷2

Y=-1

Now put the value of y in eq(1)

X=4-2+(-1)

X=2-1

X=1

Hence X=1 and y=-1

And equation (3) is wrong because in this equation has not taken (z) but you have asked the value of z
