Question:What is

5x + 19 = 6x + 12 ?

Explain how you got the answer please. :) <3

hey jen.
doing math homework?
Nope, Nope , Nope read your book the answer is in there.
First we want all the x's on one side and constants on the other. In Algebra you can do anything in an equation as long as you do the same to both sides. Think of a balanced scale... if you had the same weight to both sides, it will stay balanced.

So we have 5x + 19 = 6x + 12...

Let's subtract 6x from both sides:

5x - 6x + 19 = 6x - 6x + 12
-1x + 19 = 12

Now let's subtract 19 from both sides:

-1x + 19 - 19 = 12 - 19
-1x = -7

Now we can divide each side by -1 (dividing or multiplying by -1 just changes the sign, so...)
x = 7

We can check our answer by putting 7 back in for x:
5*7 + 19 = 6*7 + 12
35 + 19 = 42 + 12
54 = 54

So our answer is correct!

Hope this helps! :)
You need to make the sides with the same so you can subtract the 12 from both sides. It would cancel the positive 12 so the equation would be 5x+7=6x Then subtract the 5x from the 6x so it would be 7=1x or 7=x
5x + 19 = 6x + 12
First you need to isolate the variables to one side of the equation.

5x = 6x + 12 - 19
5x = 6x -7
5x - 6x = -7
-1x = -7

Solve for x.

This is basic algebra & you should be able to figure this out on your own if they let you go into this math class. Read the book & pay attention in class!
subtract 12 from both sides
subtract 5x from both sides

BAM.
that's like the easiest problem i've seen since the fifth grade.
um, how old are you again??
First, you need to get the x's on the same side of the equation.

So, subtract 5x from each side. You get:
5x - 5x +19 = 6x - 5x + 12
19 = x + 12

Now, you need to get the x by itself, so subtract 12 from each side.

You get:
19-12 = x (+12 - 12)
7 = x

Hope that helps.
I love these problems. The answer is 7. The people with seven has the correct answer.
5x + 19 = 6x + 12

6x - 5x = 19 - 12 (just transpose.you should perform any operation with same terms. note that everytime you transpose, the transposed term should change its sign.)

x = 7

check:

5(7) + 19 = 6(7) + 12

35 + 19 = 42 + 12

54 = 54
