Question

3 X + 2 Y = - 25 2X + Y =- 10

Answer 1

Hello friend

Your solution is given below :

Given that :

1st equation => 3x + 2y = - 25 ___ ( i )

2nd equation => 2x + y = - 10

Multiplying both sides by 2,

So, 4x + 2y = -50 ___________ ( ii )

Subtract (ii) from ( i) :

=> 3x+ 2y - 4x - 2y = -25 + 50

=> - x = 25

=> x = - 25

From (i ) eq.

=> y = -25 + 75 / 2
=> y = 25

So the values of

=> X = - 25
=> Y = 25
