I am so dumb. Please help someone.

It appears to be an equation.
But you need to use parenthesis to indicate whether you mean

\(\displaystyle \frac{1}{4}x+\frac{5}{2}x=22\)

or

\(\displaystyle \frac{1}{4x}+\frac{5}{2x}=22\).
 
Which one is correct?

There are two expressions in Loren's post - first one or the second one?
 
Firstb one. sorry told you I am dumb when it comes to math and computers. But thanks to everyone who is responding to help me.
 
Hi Mary:

Have you ever added fractions?. Same thing here. Make the denominators the same so you can add.

\(\displaystyle \frac{1}{4}x+\frac{2}{2}\cdot\frac{5}{2}x=22\)

\(\displaystyle \frac{1}{4}x+\frac{10}{4}x=22\)

Now, just add the fractions and solve for x. Can you do that?.
 
First how do you make the fraction look like that? I cannot seem to find the correct button for it. And would it be
1\4+10\4x=11\4=22 I told you I have no concept of math it has been 24yrs since I had to do algebra.
 
That is LaTex I am using to make it display that way. I just type the code. To see it, click on 'quote' at the upper right corner of my post.

As for the fraction, yep, you got it.

\(\displaystyle \frac{11}{4}x=22\)

Now, just multiply both sides by 4/11 and solve for x. Let me know what you get.

Why are you doing algebra now? Back to school? Online course?

You started off with: "What is this? And how do you solve it? 1/4x + 5/2x = 22"
If you didn't know that it's a simple equation, then you're really starting from scratch.
And it's just about impossible to "teach" at this site.

5/2x= 29.333333-----
5/2x[sup:248nmu8o]2[/sup:248nmu8o] = 29.33333

x[sup:248nmu8o]2[/sup:248nmu8o] = 11.72?????



i dont knowww.

What is this ?



\(\displaystyle \frac{1}{4}x+\frac{10}{4}x=22\)

\(\displaystyle \frac{11}{4}x=22\)

\(\displaystyle 11x=88\)

\(\displaystyle x=\frac{88}{11}\)

\(\displaystyle x=8\)
 
maryfornes said:
What do you mean both sides by 4\11? You mean both fractions with the 4\11?
Click to expand...

If we multiply both sides by the reciprocal of 11/4, then we isolate the x on the left side. Remember, any fraction multiplied by its reciprocal is 1.

In this case:

\(\displaystyle \frac{4}{11}\cdot\frac{11}{4}x=22\cdot\frac{4}{11}\)

\(\displaystyle x=\frac{88}{11}=8\)

See a little better now?.
