represent the following equations as one variable on number line and as two variables on the graph
(a) 2x-8=4-x

Answer :

1 )  First we form a table for both equations " 2x - 5y = - 1  And 6x - 5y = 3 "  , As :
2x - 5y = - 1    6x - 5y = 3  
x y x y
0 0.2 0 -0.6
 -0.5 0 0.5 0
-2 -0.6 1 0.6
0.5 0.4 -0.5 -1.2
2 1 -1 -1.8

Now we draw these points on x  - y plane , As :

You can take reference of this solution and solve rest of the question by yourself , or send these question in separate thread , So we can help you precisely  .
