Question

(i) 53x +977 = 247; 97x + 53y = 203.
find the values of x and y​

Answer 1

Step-by-step explanation:

53x + 97y = 247 -----(1)

97x + 53y = 203 -----(2)

समी.(1) - (2) से

-44x + 44y = 44

-x + y = 1

x - y = -1

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

x का मान समी.(1) में रखने पर

53(y-1) + 97y = 247 53y - 53 + 97y = 247

150y - 53 = 247

150y = 300

y = 2

x = 2 -1

x = 1
