7 times a number decreased by 4 is the same as 6 plus twice that number
my answer - 7n - 4 = 6 + 2n
am i correct and can you help me solving it, please!!! thank you! :)
Yes, your equation is correct.
7n - 4 = 6 + 2n
7n - 2n = 6 + 4
9n = 10
n = 10/9 = 1 1/9
Thank You! :)
You can delete my other post (sorry about that...)
You're welcome.
Yes, you are correct in setting up the equation using "7 times a number decreased by 4" and "6 plus twice that number." The equation is:
7n - 4 = 6 + 2n
Now, let's solve it step-by-step:
Combine like terms:
7n - 2n = 6 + 4
Simplify:
5n = 10
Divide by 5:
n = 2
Hence, the solution to the equation is n = 2.
