Lily has 4 fewer ribbons than Dora. Lily has 7 how many ribbons Dora have.

Dora has 11 ribbons

Step-by-step explanation:

let's say Dora has D ribbons.

let's say Lily has L ribbons

using what's given, you can make the following equation:

D - 4 = L

add 4 to both sides of the equation

D - 4 + 4 = L + 4

D = L + 4

now substitute L for 7. (given)

D = L + 4

D = 7 + 4

D = 11

Let the number of ribbons with Dora be x .

Number of ribbons with Lily = x - 4

Number of ribbons with Lily = 7

This can be written in an equation as :-

Which means Dora had 11 ribbons as ( x = number of ribbons with Dora ) .

Therefore , Dora has 11 ribbons .
