Solve it graphically: 3x + 4y= 10,

2x- 2y=2
Both the equation in two lines in one graph

Answer :
We have our equation :

3x  + 4y  =  10 
And
2x  - 2y  =  2

We for a table for different values of  x and y :
 

3x  + 4y  =  10		2x  - 2y  =  2
x	y	x	y
0	2.5	0	- 1
2	1	1	0
3.33	0	2	1
- 2	4	- 2	- 3
6	- 2	6	5

Now we form our graph , As  :

So,

We have solution :

x  =  2
And
y  = 1                               ( Ans )
