Question

B) Solve the pair of linear equations 3x + 5y = 8 and x + 2y = 10
graphically.​

Answer 1

Answer:

first we put x=0 in eq.1 then y =8/5

& then put y=0 again in eq.1 we get x=8/3

polt this in graph and draw the line this form a straight line graph

now in eq.2

put x=0 ,y=5 & then put y=0 so x=10 again plot it on graph

the cutting point which we found is the ans of the que

Answer 2

Answer:

3x+5y=8+x+2y=10

3x-X+5y-2y=10-8

2x+3y=2ans
