How to write an equation and use the distributive property .

Distributive Property

The distributive property states that when a factor is multiplied by the sum of two numbers, you can multiply each of the two numbers by that factor and then add them.

10(x + 2) = 45

Apply the distributive property to the left side of the equation by multiplying

two numbers inside the parentheses by 10

10(x) + 10(2) = 45

Now add them

10x + 20 = 45

Rearrange the like terms

10x = 45 -20

10x = 25

x = 25/10

x = 2.5
