Question

R का मान ज्ञात करो जिनके लिए समीकरण युग्म Rx-y=2,6x-2y=3 का कोई हल न हो​

Answer 1

Answer:

RX-Y=2

6X-2Y=3

IN SECOND EQUATION SIMPLYIFYIJG

3X-Y=1.5

-Y=1/2 = Y= - 1/2, NOW SOLVING

6X - 2×1/2=3

6X - 1 = 3

6X = 4 = 3X = 2

X = 2/3

NOW WE KNOW THAT Y = -1/2 AND X =2/3

R × 2/3 -(-1/2)=2

R × 2/3 + 1/2 = 2

R × 4/6 + 3/6 = 2

7r/6= 2 = 7r = 12

r = 12/7

ANSWER IS R=12/7

VALUES:R=12/7

Y=(-1/2)

X = 2/3
