Answer:
x=6, y=2.5
Step-by-step explanation:
As you can see in the denominator, the values keep on multiplying by 2, meaning that the number must multiply by 0.5 or 1/2 to get the next one.
So the rule is *1/2.
Answer:
x = 10, y = 30
Step-by-step explanation:
Since this already has a y-value, which is 3x, we will use substitution.
3x + 7x = 10
10x = 10
x = 10
Now that we know x, we can figure out what y is.
y = 3(10)
y = 30
