Answer:

It has infinite solution

Step-by-step explanation:

y = 2x +10 is already in slope intercept for so we move on to 3y-6x= 30.

The slope of 3y-6x =30 is 2 and if you solve for y, it's going to be 10.

If you put it in slope intercept form, it's going to be y = 2x+10 which is the

same as the first one.
