Question

If 3x + 2y = 8 ; 2x + 3y = 7 then find x+y & x-y​

Answer 1

Answer:

$\bold\red{Answer}$

3x + 2y = 8 --------(1)

2x + 3y = 7 --------(2)

Using (1) and (2)

3x + 2y + 2x + 3y = 8 + 7

5x + 5y = 15

5 (x+y) = 15

x + y = 15/5

x + y = 3

Answer 2

Answer:

3,1.

Step-by-step explanation:

3x+2y=8

3x=8-2y

x=8-2y÷3

substitute x=8-2y÷3 in 2x+3y=7

then 2(8-2y÷3)+3y=7

By solving it we get y=1.

then x=8-2÷3=2.

1. So, value of x+y = 2+1=3
2. x-y = 2-1=1.
