Answer:

infinite solutions

Step-by-step explanation:

x+2y=10

6y=-3x+30

To solve for x  and y we use substitution method

LEts solve the first equation for x

x+2y=10

Subtract 2y on both sides

x=10-2y

Now plug in x in second equation

6y=-3x+30

6y=-3(10-2y)+30

6y=-30+6y+30

6y=6y

Both sides are same , so both x  and y have infinite solutions.
