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

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
