Question

Solve following by Elimination :-

5x-2y-16=0 , 8x-3y-25=0

Answer 1

Step-by-step explanation:

Answer is given in the picture

Answer 2

$\textbf{\underline{\underline{According\:to\:the\:Question}}}$

5x - 2y - 16 = 0 ......... (1)

8x - 3y - 25 = 0 ......... (2)

$\textbf{Solve\;this\;by\;Elimination\;Method}$

★In that case :-

★Multiply (1) by 3 and (2) by 2

$\bf{5x - 2y - 16 = 0 \\ \\ 8x - 3y - 25 = 0}$

★Subtracting we get :-

-x = -2

$\fbox{Negative\;sign\;will\;be\;cancelled}$

★Hence we get :-

x = 2

$\textbf{Now\;substitute\;the\;value\;in\;(1)}$

5(2) - 2y - 16 = 0

10 - 2y = 16

-2y = 16 - 10

-2y = 6

$\tt{\rightarrow y=\dfrac{6}{-2}}$

y = -3

★Hence we get :-

★The two values of x and y

$\fbox{x = 2\;and\;y = -3}$
