Question

The solution of the simultaneous equations x+y =12 and x-y=2 is​

Answer 1

Answer:

x+x+y-y=12-2=10x-y

Step-by-step explanation:

this is your ams

Answer 2

Answer:

x + y = 12 ---- 1

x - y = 2 ----2

add equation 1 and 2

x + y = 12

+ x - y = 2

----------------

2x = 14

x = 14/2

x = 7

put x = 7 in equation 1

x + y = 12

7 + y = 12

y = 12 - 7

y = 5

( x,y ) = ( 7,5)
