School X and School Y play each other in a competition.
School X has eight more points than School Y.
School X has three times as many points as School Y.
How many points does each school have?

Answer 1

Let school X has y points and school Y has x points, than

y=x+8

y=3x

left sides of equations are y, so

3x=x+8

2x=8

x=4

School Y has 4 points, so school X has

4+8=12 points or 4×3=12 points.

Answer:

School X -- 12 points

School Y -- 4 points
