Question

solve the following pair of linear equations by the substitʊtion method.3×-ʏ=3
9×-3ʏ=9 ​

Answer 1

Answer:

infinite number of points

Step-by-step explanation:

given ,

9x-3y= 9 and 3x-y = 3by comparing coffficents we get eq-1 is same as eq -2

... -(or)-

3( 3x-y-3) =(9x-3y-9)

so eq 1 coincides with eq-2

therefore there are infinite number of common points
