Question

3x + 2y = 5 , 4x + 5y = 2 elimination method ​

Answer 1

Answer:

y=-2 and x=3

Step-by-step explanation:

Multiplying eq.1 by 4 and eq.2 by 3

12x+8y=20-------i

12x+15y=6------ii

now change the signs

12x+8y=20

-12x-15y=-6

=-7y=14

y=14/-7

y=-2

Now substituting the values

12x+(8*-2)=20

12x-16=20

12x=20+16

12x=36

x=36/12

x=3
