X + y = 4; 2x - y = 2. solve by graphical method |
|
Answer» Answer: In GRAPHICAL method,we take values by own so,you can put values in the equation like let x+y=4 as eq.1ST and 2x - y = 2 as eq.2nd by PUTTING x=1 then y=3 in equation 1st by putting x=2then y = 2 in equation 1st we can take negative values also like by putting x=5 then y = -1 in equation 1st (x,y)=(1,3),(2,2),(5,-1) SIMILARLY for 2nd equation (x,y)= (1,0),(2,2),(-1,-4) hopefully it's helpful |
