Question

2) Solve the following simultaneous equations using graphical method. 2x + y = 6; 4-3x/4=y.

​

Answer 1

Answer:

2x + y=6

4-3x/4=y

2x=6-y

x=6-y/2

4-3x/4=y

putting the value of x in the above equation

4-3(6-y/2)/4=y

4-18+3y/2/4=y

4-4(18+3y)/2=y

4-72+12y/2=y

-68=2y-12y

-68=-10y

68/10=y

6.8=y

x=6-y/2

x=6-6.8/5

x=0.8/5

x=40/10

x=4
