So.... How about a math question?

[Jinxzy]

I've been sitting here thinking about some math problems to help me study for our basic math test but one problem my friend game me I cant figure out. Can you solve it?

16x+3 = -14 What is X?

 

[Quaxar]

16x+3 = -14 |-3
16x = -17 |:16
x = -17/16

Correct me if I'm wrong.

 

[Jinxzy]

16x+3 = -14 |-3
16x = -17 |:16
x = -17/16

Correct me if I'm wrong.

same thing I got but my friend keeps saying it's wrong. She says it's 1.something.(her words not mine)

 

[SomeLameStuff]

Math isn't really my strongest subject, but I'll give it a go


16x+3 = -14

16x = -14-3

16x = -17

x = -17/16

x = -1.0625

Unless you're trying to find X and not x, then I'm not sure.

Math makes my thinker box hurt

Well unless you're missing a negative sign somewhere or modulus is involved I don't really see how it can be a positive number...

You're both right. -17/16=-1.0625

 

[Woodsey]

16x+3 = -14 |-3
16x = -17 |:16
x = -17/16

Correct me if I'm wrong.

Well yeah, -17/16 will be 1. something. Or -1. something actually.

16x+3 = -14 <=>
16x = -14-3 = -17 <=>
x= -17/16 = -1.0625

 

[hyperhammy]

16x+3 = -14 (-3)
16x = -17 (/16)
x= -1.0625

 

[SnootyEnglishman]

16x+3 = -14

First ye take the 3 and switch it over and make it a negative number.

16x= -14-3

Then combine the like terms on that side.

16x=-17

Divide -17 by the co-efficient of X.

x=-17/16

That is your answer. If you want to be technical (or to get your friend to shut up) the answer is

x= -1.0625

ture but I only needed the fraction. trying to keep it simple.

x = -17/16

Correct me if I'm wrong.

She be trolling. Tell her that it's equal to 2 and ask her to disprove you with her workings.

 

[DuplicateValue]

This was a fairly simple question...

What year are you in?

Here's one for ya.

From 1 to the cube root of 3,
Times the cosine,
Of 3 pi over 9,

Assuming your friend said -1.0625, both of you are correct. I don't see how you could be mistaken, unless the question specified a decimal answer instead of a fractional answer or vice versa.

 

[Amethyst Wind]

How about a simultaneous equation:

4x + 7y = 136
10x + 15y = 330

Find x and y. (There may or may not be more than one correct answer)

 

[Quaxar]

16x+3 = -14 |-3
16x = -17 |:16
x = -17/16

Correct me if I'm wrong.

How about checking her equations? Because if she claims it's a positive number there has to be something wrong. Unless she solved for -x, but that would be a bit strange.

 

[2xDouble]

X is a variable, indicating an unknown numerical quantity, range, or expression.

Spoiler: Also this guy

HAHAHA!! but seriously...

He's right.

 

[Hr Habberdasher]

if f(x)= 3x^3 + 4x^2 +2
what does f'(x) equal?
