Question

prove that pair of linear equations x+y=5, 2x+2y = 10 have infinite Solutions​

Answer 1

Answer:

The lines are coincident and the pair of equations is dependent and consistent.

Step-by-step explanation:

We are given the following in the question:

Writing the equation in general form:

Condition for consistency:

 

Putting values, we get,

Thus, the lines are coincident and the pair of equations is dependent and consistent.

The, lines have infinitely many solutions.

Check whether the pair of equations 2x+y-5=0,3x-2y-4=0are consistent or inconsistent graphically, find the solution if the equation are consistent

Answer 2

Step-by-step explanation:

x+y=5

2x+2y=10

if equation 2 is divided by 2

the answer is x+y=5

a1/a2=b1/b2=c1/c2

so that they have infinite solutions
