Question

for simultaneous equations in variable x and y Dx = 49, Dy = -63 D = 7 then what is x

Answer 1

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.

Answer 2

Simultaneous equation in the form of variable x and y is equal to 49Dy IS EQUAL TO -63 D AND IS EQUAL TO 7 the value of x and y would be  

and D is determinant,

x=DXD=49/7

x=7

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

y=-9

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