Question

find the value of X and Y from the equal ordered pairs
(x+y,3x-2y) = (16,12)​

Answer 1

Answer:

x+y = 16 .......(1)

3x-2y = 12

multiply 2 in eq 1 and add both

2x+2y = 32

3x-2y = 12

we get 5x = 44

x = 44/5

Put x in eq 1

y = 16-44/5 = 80-44/5 = 36/5

Answer 2

Answer:

x+y=16,3x-2y=12

3x-x+2y-y=16+12

2x+y=28

x+y=28/2

x+y=14
