TOPIC: Math Test

Here is a math test about quations

3(3x+1)=3(4x-5)

21.

Sorry, I had to do it. First time too.

(18 + 1) = 19 * 3 = 57
(24 - 5) = 19 * 3 = 57

6 goes in to 24 4 times, 6 goes into 18 3 times
x = 6

Right!

I took

3(3x+1)=3(4x-5)

9x+3=12x-15

9x+3-9x=12x-15-9x

3=3x-15

3+15=3x-15+15

18=3x

18/3=3x/3

x=6

I hope it's right to count it out

Hahaha it's not my homework i have test tomrrow i just want to know if you guys can it!

YOU GUYS ARE ALL WRONG!

LET THIS ASIAN DO IT!

3(3x+1)=3(4x-5)

9x+3=12x-15

9x+3-9x=12x-15-9x

3=3x-15

3+15=3x-15+15

3=3x

3/3=3x/3

x=6 (YOU FORGOT TO DIVIDE BY 2!)

x=6/2

x=3

Awesome bro!

I have a math test tomorrow but Its not the same stuff. We are doing Advanced GCSE Math to pass the 1st semester in MYP (Middle years program, International Baccalaureate.) I am in a different school system than the UK or US so I put the GCSE as a persepctive. (I am in Grade 8 (US) or Year 9 (UK)

New question, you need to use trial and improvement to find the solution:

Find the answer to the equation x³ – 2x = 25 to one decimal place.

Good luck

Alright m8

X*X*X = 3x

3x - 2x = 1x

x=25

Nevermind, used the power of google.
Either way works.

No. Do the math, 25^3-50 isn't equal to 25...

The equation has x^3 thus there should be three solutions. This specific equation can't be solved in R, only in imaginary numbers which I didn't learn yet

This gives me a headache.

What

3.2

The internet knows.

Hmm
let me make it easy

437+X=450

X= ?

X= 450-437

X= 23

X= 437+23=450
