(5, 1)
no solution

Answer 1

@robtobey

Answer 2

there are two methods :-
1) to solve it by graphical method ( long method)
2) by algebraically ( short method )

Answer 3

short method

Answer 4

\[\large \bf x-y=4\]
\[\large \bf x=4+y\]

Answer 5

put this value of x and plug in the first equation !

Answer 6

we do this because we need to solve two equations and to find ordered pair ( common) , we use this ^^

Answer 7

understood ? @kaley246

Answer 8

Answer 14

ok robtobey help please

Answer 15

ok @robtobey help please

Answer 16

Sorry. The first posting had an error.

x+y=6
x-y=4
---------
2 x = 10
x = 5

Answer 17

To find y:

5 + ? = 6
5 + y = 6
y = 1
