I have an algebra problem every day, whether it be an equation, a word problem, an operation, or another. PM me the answer, and I'll tell you the answer here the next day. I'll also list who gave me what answer, and if it is right or wrong.

Day 1: 2X + 6X - 4 = 5X + 7 - 2

E: as you can see I stink at updating this so the problems are only occasional now.
 
Re: Daily Algebra Problem

Is this a clever ruse just to get us to do your homework? :smug:
 
Re: Daily Algebra Problem

2X + 6X - 4 = 5X + 7 - 2
8X - 4 = 5X + 5
8X - 5X = 5 + 4
3X = 9
X = 3

i know walkazo already did this but i don't care

Click to expand...
2X + 6X - 4 - 5X = 7 - 2
2X + 6X - 5X = 7 - 2 + 4
3X = 7 - 2 + 4
3X = 5 + 4
3X = 9
3X/3 = 9/3
X = 3

Re: Daily Algebra Problem

I already PM'd Roy Koopa before all of you posted here, so.....

Re: Daily Algebra Problem

If you give the answer the next day, I don't see the point of this thread.
 
Re: Daily Algebra Problem

for people to do before he posts the answer ?????

Re: Daily Algebra Problem

2X + 6X - 4 = 5X + 7 - 2

2/5X + 6 X - 4 = + 7 - 2

2/11X = - 4 + 7 - 2

> X = 2/11

I'm 100% convinced that this is correct. inb4 somebody thinks im serious
 
Re: Daily Algebra Problem

Check your answer by substituting the Xs for your answer

It's wrong, btw. 3 is the answer. I checked. 20 = 20
 
Re: Daily Algebra Problem

The answer was, in fact, X=3.

Correct:

Day 2: Multiply.

3AB + 8BC
-6AB - BC
-------------
 
Re: Daily Algebra Problem

(3AB + 8BC)(-6AB - BC)
= -18A2B2 - 3AB2C - 48AB2C - 8B2C2
= -18A2B2 - 51AB2C - 8B2C2

?
 
Re: Daily Algebra Problem

(3AB + 8BC) (-6AB - BC)

= 11ABBC -7ABBC

= 4 ABBC

> 4 AB²C

I gotta be correct this time around!

wait its actually multiply

hold on

i think it went sth like this then

11ABBC * (-7ABBC)

= -77ABBC

>-77AB²C
 
Re: Daily Algebra Problem

maybe sometime
 
Re: Daily Algebra Problem

Here they come

I'm typing other things right now so yeah

I have three for 12th 13th and 14th.

12th:

Find three consecutive numbers so that three times the first is equal to six less than the sum of the other two.

13th:

a=1, b=3, c=4, d=-2, e=-1, f= 1/2, g=7

ab + g
-------- - [bde(f)]
d

14th:

3x + (2x - 4) = 5x
 
Re: Daily Algebra Problem

legit time:

3a = (b + c) - 6
c - b = 1
b - a = 1

> b = 1 + a

>> 3a = (1 + a + c) - 6

>c = 1 + (1 + a)

>> 3a = (1 + a + 1 + 1 + a) - 6

>> 3a = 3 + 2a - 6

>>> a = -3

>>> b = -2

>>> c = -1



((3 + 7) / -2) - 3

>-5 -3

>> -8



2x - 4 = 2x

> -4 != 0

>> no solution.
