Question

2x+5=-25 and -3y-6=48, then xy is??​

Answer 1

Answer:

Given equations are,

3x+2y+25=0................(i)

2x+y+10=0...................(ii)

From (ii), we can get

y=−2x−10

Substitute y value in equation (i) , we get

3x+2(−2x−10)+25=0

⇒3x−4x−20+25=0

⇒−x+5=0

∴x=5

Hence,

y=−2x−10=−2(5)−10=−10−10=−20

Solution is (x,y)=(5,−20)
