Question

equation 3 x minus y equal to 3 and equation to 9 x minus 3 Y equal to 9 in elimination method​

Answer 1

Hey mate thank for the question

Hope it helps

ATP=>

3x-y=3--------(1)

9x-3y=9-------(2)

Multiplying eq (1) by 3 and subtracting

9x-3y=9

9x-3y=9

- + -

--------

0

Answer 2

solution:-

3x-y= 3…..................…(1)

9x-3y=9

3( 3x-y)=9

3x-y= 3..........................(2)

from (1) and (2) we see that all the coefficients of x and y in both eqns are equal and there values in RHS are also equal.

therefore

when eliminate y itself from(1)

or from(2)

this is possible only when y=0

eqn=>. 3x= 3

x= 1.

when eleminate x itself from(1)

or from(2)

this is possible only when x=0

eqn=> -y= 3

y= -3

answer is (x,y): ( 1,0) 0,-3)

but this eqn represents a line segment and values of x and y are represented by coordinate of all points lie on this line segment.
