Answer:

It is an Linear equation Sum

Hope so you get the answer ☺️

Answer 2

Answer:

5x- 2y = 10

5x -2y - 10 = 0 ...(1)

3x+y = 17

3x + y - 17 = 0 ....(2)

from (1) or (2)..

X. Y. 1

__________ = ____________ = ___________

b1c2- b2c1 c1a2- c2a1. a1b2- a2b1

X Y 1

-2(b1). -10(c1). 5(a1). -2(b1)

1 (b2). -17(c2). 3(a2). 1(b2)

X Y 1

____________ = ______________ = ____________

(-2*-17)-(1*-10). (-10*3)-(-17*5). (5*1)-(3*-2)

X. Y. 1

_____________ = _____________= _____________

34-(-10). -30-(-85). 5-(-6)

X. Y. 1

_____________ = ______________ = ____________

44. 55. 11

so, X = 44/11 = 4

and, Y = 55/11 = 5
