Question

The pair of linear equations 8x - 5y = 7 and 16x – 10y = 14 have;

a) One solution

b) Two solution

c) Many solutions

d) No solution​

Answer 1

Answer:

c) many solutions

Step-by-step explanation:

8/16=5/10=7/14=>1/2=1/2=1/2 => infinitely many solutions

Answer 2

Answer:

no solution

Step-by-step explanation:

8x-5y=7

16x-10y=14

upper equation can be multiplied by 10 and the lower can be multiplied by 5

so we get

80x-50y=70

80x-50y=70

now when we will change the signs of the lower equation

we will get

80x-50y=70

-80x+50y=-70

so while adding both the equations everything will get cancel out

amd hence there will be no solution
