Answer 2

Step-by-step explanation:

Hi dear, here's your answer.

If your in question D refers Determinant then,

x=Dx/D=49/7=7

y= Dy/D=-63/7-9

HOPE IT HELPS.

MARK IT AS BRAINLIEST PLZ.

Simultaneous equation in the form of

variable x and y is equal to 49Dy IS EQUAL

TO-63 D AND IS EQUAL TO7 the value of

x and y would boe

and D is determinant,

x=DXD=49/7

x=7

yDy/D=-63/7=-9

y-9

value of x is 7 and y is -9!!
