3(1+4n)-2(5n-3)=25
please help me and write all the steps if you can.......
Steve has shown you how to do this kind of problem. Now it's your turn.
He has???? where
See the questions you posted using the name lol.
To solve the equation 3(1+4n) - 2(5n-3) = 25, you need to simplify the expression on both sides of the equal sign and then isolate the variable, n. Here are the steps:
Step 1: Distribute the terms inside the parentheses.
3(1+4n) - 2(5n-3) = 25
3 * 1 + 3 * 4n - 2 * 5n + 2 * 3 = 25
3 + 12n - 10n + 6 = 25
Step 2: Combine like terms.
12n - 10n = 2n
3 + 6 = 9
Step 3: Simplify the equation further.
2n + 9 = 25
Step 4: Isolate the variable by subtracting 9 from both sides.
2n + 9 - 9 = 25 - 9
2n = 16
Step 5: Divide both sides of the equation by 2.
2n/2 = 16/2
n = 8
So, the solution to the equation 3(1+4n) - 2(5n-3) = 25 is n = 8.
