Question

Q8: Solve for x and y 3x + 2y + 25 = 0 ,
x + y + 15 = 0
on Gind three numbers in AP whose sum is 21 and their product​

Answer 1

Answer:

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

x+y+15=0

→x=−15−y ---------- (ii)

Substituting the value of x in equation (i) we get,

→3(−15−y)+2y+25=0

→−45−3y+2y+25=0

→−y=−25+45

→y=−20

Putting the value of y in eqn (ii) we get,

x=−15−(−20)

→x=−15+20

→x=5
