Answer:
School X: 8 points School Y: 2.6̅ or 6 repeating.
Step-by-step explanation:
When you know that School X has <em>8 points</em>, and School Y has <em>3 times less</em>, you have to divide 8 by 3. When you do that, you get 2.6̅, or 2.6 repeating, which means that you have 2 that goes into 3 goes into 8 3 times, because 3 x 3 would be 9, which is bigger than 8. Anyway, when you divide again because you have to add a decimal point after the number to keep dividing, <em>you keep getting 6</em>. it's never going to change, because thats what 6̅ is. 6 REPEATING.
I hope this helps! ;)
3x - 7 = 5x - 13
-3x -3x
5x - 3x = 2x
-7 = 2x - 13
+7 +7
-13+7 = -6
2x = -6
2x/2 = -6/2
x = -3
Answer: x = -3
