Whats the value of n if the equation is 3n-15=7n+n

n=-3

Step-by-step explanation:

So first, you have to add 7n and n

There is a implied one there

you subtract 8n to both sides, and add 15 to both sides

that leaves this:

-5n=15

you divide by -5, and you get your answer as

n=-3

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
