please help 3(n+1)=5(n-3) thank you
3(n+1)=5(n-3)
3n + 3 = 5n - 15
3n - 3n + 3 = 5n - 3n - 15
3 + 15 = 2n - 15 + 15
18 = 2n
? = n
thanks and one more thing -4=c-3/6-1-c/8+c/12
You need to show where parentheses go in that last equation. Even though they may not be in your printed assignment, you need them here when typing equations on a single line, without spaces.
Do you mean
-4 = (c-3)/6 - (1-c)/8 + c/12 ?
To solve the equation 3(n+1) = 5(n-3), we can follow these steps:
Step 1: Distribute the multiplication:
3n + 3 = 5n - 15
Step 2: Combine like terms:
3n - 5n = -15 - 3
-2n = -18
Step 3: Divide both sides by -2 to isolate the variable:
n = (-18) / (-2)
n = 9
So the solution to the equation is n = 9.
