6x + 7 = 25
6x = 25 - 7
6x = 18
x = 18/6
x = 3

u turn ur data into an equation and solve for the missing variable....which, in this problem is x and it represents the number Maria was thinking of.

Answer 2

Answer: 3

Explanation:

Let x be the number which Maria was thinking of.

Then considering the given statement , we have the following equation:-

`6x+7=25`

To solve the above equation, we first subtract 7 on both the sides , we get

`6x=18`

Now, divide 6 on both the sides , we get

`x=3`

Hence, maria'a number is 3.
