Answer 2

link will explain step by step :)

Answer 3

Okay ty dear!

Answer 4

np cx

Answer 5

lets try an eliminate subtract the 2 equations ( we wouldn't normally do this0
x + y = 16
x + y = 2
0 + 0 = 14
0 = 14

Answer 6

which, of course is rubbish

Answer 7

we got this result because x + y cannot be both equal to 2 and to 16

Answer 8

so what do you think the correct answer is?

Answer 9

do you follow that ?

Answer 10

when you subtract equations you do it term by term
x - x = 0, y -y = 0 and 16 - 2 = 14

Answer 11

I know its usual to fix things so that you add instead of subtract but in this simple case its really not necessary
it will have 1 more step

Answer 12

x + y = 16
x + y = 2
multiply second equation by -1;-
-x - y = -2

now add

x + y = 16
-x - y = -2

0 = 0 = 14
0 = 14

Answer 13

as you cannot get any values for x and y what do you think the correct option is?

Answer 14

the first 3 must be incorrect , right?
