Question

solve for X and Y in elimination method​

Answer 1

Answer:

Step-by-step explanation:

X-3y = 0........×3

3x-9y=0.....1

3x-9y=2........2

On changing signs

0 = -2

Answer 2

$\textbf{Here is your answer}$

$\textbf{Given}$

X - 3Y = 0 ----------(1)
3X - 9Y = 2 -----------(2)

$\textbf{Now}$

(1)×3 and (2)×1

$\textbf{Therefore}$

3X - 9Y = 0
3X - Y = 2
(-) (+) (-)
------------------
- 8Y = - 2
=> Y = $\frac{1}{4}$ (- and - cancel)

$\textbf{Now}$

From (1) we get,

3X - 9Y = 2

=> 3X - 9×$\frac{1}{4}$ = 2

=> 3X = 2 - $\frac{9}{4}$

=> 3X = $\frac{-1}{4}$

=> X = $\frac{-1}{12}$
