10x + 8y = 16 has no solution. 1-

Answer 1

Answer:

For the given pair of equations

a₁/a₂=5/10=1/2

b₁/b₂=4/8=1/2

c₁/c₂=20/16=5/4

As the given pair of linear equation satisfies -

a₁/a₂=b₁/b₂≠c₁/c2

1/2=1/2≠5/4

The graph will be a pair of parallel lines and so the pair of equations will have no solution.

Answer 2

Answer:

$\huge{\boxed{\rm{\red{They have no solution}}}}$

Step-by-step explanation:

Given linear equations are

5x+4y=20

=>5x+4y-20=0-----(1)

a1=5;b1=4;c1=-20

10x+8y=16

=>2(5x+4y)=16

=>5x+4y=16/2

=>5x+4y=8

=>5x+4y-8=0.....(2)

a2=5;b2=5;c2=-8

a1/a2=5/5=1

b1/b2=4/4=1

c1/c2=-20/-8=5/2

a1/a2=b1/b2≠c1/c2

so Given lines are inconsistent or parallel lines with no solution.
