3) For simultaneous equations in x & y, if Dx = 49,Dy =
-63 and D = 7 then what is the value ofx? (x वy ही चले
असलेल्या एकसामायिक समीकरणासाठी जर D = 49,
D,= -63 आणि D=7 असेल तर x ची किंमत काढा)

Answer:
x=7 & y = -9
Step-by-step explanation:
Given Dx= 49
Dy= -63
D= 7
Find X&y
Sol:- Dx= 49
7*x= 49
x= 49÷7
x = 7
Again, Dy = -63
7*y = -63
y= -63÷7
Y = -9
