Question

if 2x+3y=14 and 2x-3y=2 find the value of xy​

Answer 1

Step-by-step explanation:

On add both eqa then we get

→4x=16

→x=4

•°•then put the value x in 1 equa

→2×4+3y=14

3y=14-8

→y=2

•°•then x=4 and y=2

Answer 2

Answer:

Hey mate here is your answer ⬇️

2x + 3y = 14 - - - - - - - - i

2x - 3y = 2 - - - - - - - - - ii

Adding eq i and ii

2x + 3y + 2x - 3y = 14 +2

4x = 16

x = 4

Putting the value of x in eq. i, we get;

✪2x + 3y = 14

➯2(4) + 3y = 14

➯8 + 3y = 14

➯3y = 14 - 8

➨ y = 6/3 =2
