    An equation has an equal sign in it. x = 1<-- equation x + y = 2 <-- equation 2y - 5 = 9 <-- equation

    h is a variable. Basically, h can be any number. For example, 13 x h = 103 Just replace h with any number you want 13 x 1 = 103 13 = 103, this is false because 13 does not equal 103.

    This type of math is called algebra. It is very simple. Please, view this link to understand what these, "letters," mean. They can be confusing at first, but they're actually very easy to understand. http://www.mathsisfun.com/definitions/variable.html

    ok the one that i was wondering about thirteen multiplied by h is one hundred and four can u explain that one

    Okay, so lets focus on the first part of this word problem. It's saying thirteen is being multiplied by h. Basically, h is a variable. H can be any number, we don't know what h is currently, but we do know it's being multiplied by h. So, "Thirteen multiplied by h," would be: 13 x h <-- Now this is equal to 104. 13 x h = 104 <-- Because the equation tells us 13 times h is equal to 104.

    how do you come up with h is equal to 104 ?

  27. Compassionate

    Because, " thirteen multiplied by h is EQUAL TO ONE HUNDRED AND FOUR."

    so do i have to find a number that is multiplied by 13 to make 104

    13 x h = 104 13 x 1 = 13 <-- this is not 104 13 x 2 = 26 <-- this is not 104.

    Yes! So y is just any number that can be multiplied by 5 to equal 25.
