Mrs. Hines has 40 ballons for a party. She has 12 more balloons than she had for her last party. How many balloons did she have last party? Is there a different equation you can write to show this problem? Explain

28

Step-by-step explanation:

Let the number of balloons that she had last party be represented by x.

Since Mrs.Hines has 40 ballons for a party which was 12 more balloons than she had for her last party. The number of ballons had last party will be formed into an equation as:

x + 12 = 40

Collect like terms

x = 40 - 12

x = 28

She had 28 balloons last year

step-by-step explanation:

if x = 2 you have to find x to finish the problem
