Question

Complete the table for the given rule.

Rule: y= x - 5

X= ?,?,15
Y= 7,25,?

Answer 1

x = 12, 30, 15

y = 7, 25, 10

Explanation:

y = x - 5

When y = 7,

7 = x - 5

Add 5 to both sides

7 + 5 = x - 5 + 5

12 = x

When y = 25,

25 = x - 5

25 + 5 = x - 5 + 5

30 = x

When x = 15,

y = 15 - 5 = 10
