Question

3x+2y=5 and 2x+3y=5 then x+y =?​

Answer 1

Answer:

x + y = 2

Step-by-step explanation:

3x + 2y = 5 ----->(1)

2x + 3y = 5 ----->(2)

Add (1) and (2)

3x + 2x + 2y + 3y = 5 + 5

5x + 5y = 10

5 (x + y) = 10

x + y = $\frac{10}{5}$

x + y = 2

Answer 2

Answer:

2

Step-by-step explanation:

3x + 2y = 5 ------eq1

2x + 3y = 5 -------eq2

add eq1 and eq2

(3x + 2y) + (2x + 3y) = 5 + 5

5x + 5y = 10

5(x + y) = 5(2)

x + y = 2
