Question

13. If 2x+3y=12 and 3x-2y=5 then
1 poir​

Answer 1

Answer:

x=3 y=2

Step-by-step explanation:

2x+3y=12 (×3) to eliminate x

3x-2y=5 (×2) to eliminate x

taking lcm

6x+9y=36

6x-4y=10

by elimination method

6x +9y-6x +4y=36 -10

13y=26

y=2(proved)

hence

2x+3y =12

2x + (3×2)=12

2x+6=12

2x=12-6

2x=6

x=3

hence value of x=3 . y=2
