Question

4x - 9y = 0 , 3x + 2y - 35 = 0​

Answer 1

Step-by-step explanation:

4x-9y=0

3x+2y=35 by multiplying equation 1 by 3 and equation 2 by 4 and subtracting we get:

12x-27y=0 - 12x+8y=140

then,y =4 and x=9

Answer 2

Step-by-step explanation:

4x - 9y = 0

3x + 2y - 35 =0

=> 3x+2y=35

multiply the first expression with 3 and the second expression with 4

so the first expression will be 12x-27y=0 and the second expression will be 12x+8y=140

Subtract the two expressions

 12x - 27y = 0

-12x - 8y = -140

we get -35y=  -140

         => y = -140/-35

                 = 4

Substituting y=4 in the first expression we get

4x - 9x4 =0

4x=36

x=9

Therefore y=4, x=9
