Answer:
school x = 12
school y = 4
Step-by-step explanation:
School X has eight more points than School Y.
School X has three times as many points as School Y .
Writing these statements in terms of equation
x = y + 8
x = 3 y
Substituting the value of x in y, we get
3 y = y + 8
Taking variable on left side of equation
3 y – y = 8 (subtract y from both sides)
2 y= 8 (divid 2 from both sides)
y = 4
then plug in y to the first equation
x= y + 8
x= 4 + 8
x= 12
