Can someone help me with this math problem?

Question

5j+6=3j+15 please thanks its algebra 1 with tech.

Answer 1

5j + 6 = 3j + 15

5j + 6 - 3j = 3j + 15 - 3j

2j + 6 = 15

2j + 6 - 6 = 15 - 6

2j = 9

3j / 2 = 9 / 2

j = 9 / 2

j = 4 1/2

j = 4.5

Answer 2

Alrighty, so it's not as hard as it looks. I remember way back when I had the same problem hehe =/

So here it goes;

5j+6=3j+15 you have two equations

So lets start by moving either number (6 or 15) to the other side by doing the opposite opperation ;
5j=3j+15 - 6
5j=3j+9

Then do the same but this time for the number with the variables (5j or 3j);
5j=3j+9
5j - 3j = 9
2j = 9
j = 9/2

And that's your answer.

Answer 3

Let's take a look:

5j + 6 = 3j + 15
- 3j from both sides...

2j + 6 = 15
...now - 6 from both sides...

2j = 9
...and let's divide by 2 on both sides...

j = 4.5

Make sense?
Hope this helps!

Answer 4

Here's what you want to do.

5j + 6 = 3j + 15

It's hard to do this all at once in your head, so, let's use addition and subtraction to pile up all the j terms on the side that's got more of them to start with.
The left side's got 5 j's versus the right's only having 3 of 'em.

So, we'll >subtract< 3j from each side.

2j + 6 = 15

Now, let's subtract 6 from each side:

2j = 9

And finally, divide by 2
j = 9/2

Answer 5

5j+6=3j+15
5j+6-6=3j+15-6
5j=3j+9
5j-3j=3j-3j+9
2j=9
j=9/2= 4 1/2

Answer 6

5j+6=3j+15

subtract 3j from each side
2j+6=15

subtract 6 from each side
2j=9

divide both sides by 9
j=4.5

Answer 7

well, subtract 6 from both sides and you have 5j=3j + 9
now subtract 3j from both sides and you have 2j=9
now divide both sides by 2 and you have j=4.5
