Question

does some one have the answer to this af 3y + 9=36 true?

Answer 1

Answer:

When both equations have the same slope, but not the same y-intercept, they'll be parallel to each other and no intersections means no solutions. When both equations have different slopes than regardless of the y-intercept they'll intersect for certain, therefore it has exactly one solution.

Answer 2

Answer:

3y+9=36

3y=36-9

3y=27

y=27/3=9

hence: 3*3*3+9=36

so its right
