Question

The difference between 32.6 and a number is 10.2

Answer 1

22.4

Explanation:

First we can make an equation to find the unknown number:

Difference mean subtraction:

32.6 - x = 10.2

To do this we can subtract 32.6 from both sides to isolate -x or to make -x the subject:

32.6-x-32.6 = 10.2 - 32.6

-x = -22.4

Now we can multiply both sides by -1 to make x positive:

-(-x) = -(-22.4)

x= 22.4

Answer 2

22.4

Explanation:

Let that number be " x ".

The difference between 32.6 and a number is 10.2

32.6 - x = 10.2

Add x on both sides,

32.6 - x + x = 10.2 + x

32.6 = 10.2 + x

10.2 + x = 32.6

Substract x on both sides,

10.2 - 10.2 + x = 32.6 - 10.2

x = 22.4

Therefore,

The number is 22.4
