6x + 7 = 55
x = 8
Is this the correct answer to the following question?
"I'm thinking of a number. If you multiply it by 6 and then add 7, you will get 55. What is my number?"
Right! :-)
Yes. 6x = 48
therefore x = 8
Yes, the value of x = 8 is the correct answer to the given question.
Let's go through the steps to solve the equation: "6x + 7 = 55".
To isolate x, we need to get rid of the 7 on the left side of the equation. To do this, we can subtract 7 from both sides:
6x + 7 - 7 = 55 - 7
6x = 48
Now, we have 6x = 48. To solve for x, we can divide both sides by 6:
(6x)/6 = 48/6
x = 8
So, the value of x is 8, which means that the number in question, when multiplied by 6 and then added 7, gives us 55.
