Lisa has twice the amount of purses as Sally. If Sally has 6 purses, how many does Lisa have?=6x+6
x = -1
If Sally has 6 purses and Lisa has twice as much as that, then obviously Lisa would have 12 purses. 6*2=12.
To find out how many purses Lisa has, we can use the given information that Lisa has twice the amount of purses as Sally.
First, let's define a variable for the number of purses Lisa has. Let L represent the number of purses Lisa has.
We know that Lisa has twice the amount of purses as Sally, so we can express this information as:
L = 2 * S,
where S is the number of purses Sally has.
We are given that Sally has 6 purses, so we can substitute S = 6 into the equation:
L = 2 * 6.
Now, let's simplify the equation:
L = 12.
Therefore, Lisa has 12 purses.
