Maria was playing a game with her brother. She said "I'm thinking of a number. When you multiply my number by six and add seven, you get twenty five. What is my number? Explain.
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: 3
Step-by-step 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.
