Use your number sense to find the values for x and y that satisfy the equations2x=8

x = 4

Step-by-step explanation:

Using "number sense"

2x=8

Double a number is 8.

What is half of 8? 4.

Double of 4 is 8.

Therefore the number, x, is 4.

Check:

2x = 8

x = 8/2

x = 4

2x = 8

2 (4) = 8

8 = 8
