Answer:
3x+4y = 5 let it be the equation 1
5x-2y = -9 and this is equation 2
we multiply 5 with eq. 1 and multiply 3 with eq.2
5(3x+4y=5)
3(5x-2y=-9)
we get
15x+20y=25.....equation 3. (let)
15x-6y= -27......equation 4. (let)
by eliminating eq 3 and 4
we get
y=2
then put the value of y in any equation
and we get the value
x= -1
