Question

3) If 3x+ 2y - 16 and 2x + 3y =19 then x +y_3,-3,7,35)​

Answer 1

Answer:

7

Step-by-step explanation:

(3x+2y=16)×2=6x+4y=32.............................(1)

(2x+3y=19)×3=6x+9y=57..............................(2)

by substracting 1 from 2

5y=25

y=5

by putting y=5 in given equation

2x+3y=16

2×5+3y=16

3y=6

y=2

so, x+y=5+2=7
