2x - y=8.....1

3x + y=17....2 using elimination method

Solve
add the two equations to eliminate y.
5x = 25
now finish it off
2 x - y = 8
+
3 x + y = 17
__________

5 x = 25

x = 25 / 5

x = 5

Insert this value into the first or second equation, whichever.

For example:

3 x + y = 17

3 ∙ 5 + y = 17

15 + y = 17

Subtract 15 to both sides.

y = 2

The solution is x = 5 , y = 2

You can also write equation as ( 5 , 2 )

Where fist number is x coordinate , second number is y coordinate.
You can also write the solution of equation as ( 5 , 2 )
