Math problem?! (Sophomore Algebra)?

Question

Ok so i'm in 8th grade but i'm taking a sophomore math class! OMG!

Anyway,

−5(1 − 5x) +5(−8x− 2) = −4x− 8x

^^ Thats the problem. It's kinda easy but my brain's fried considering that today was the first day of school DX Thx for the homework mr.j. appreciated.

Answer 1

do all the multiplying first

-5 + 25x - 40x -10 = -4x - 8x  

combine like terms

-15x - 15 = -12x

get variables on one side constants on the other

-15 = 3x

solve for x

x = -5

I skipped some steps because if you are in 8th grade taking 10th grade math you probably know those steps.

Answer 2

-5+25x-40x-10 = -12x

-15x-15 = -12x

-15 = 3x

x = -5

Answer 3

Whoa! You're in 8th Grade and doing sophomore algebra. I'm in 8th too, but I'm doing Algebra I.

Answer 4

That is NOT sophmore algebra. I would know, I'm a sophmore.

Anyway, that's really easy

You just simplify it:

-5 + 25x - 40x - 10 = -4x - 8x

-15x - 15 = - 12 x

3x = - 15

x = - 5

Answer 5

I GOT X= -5

Im not 100% sure if it's right though. sorry..

you distribute the outside number of each part of the equation.

(-5+25x) + (-40x -10) = -12x

when you do the math you get -15 + (-15x) = -12x

subtract the -15x from -12x and you get 3x

divide the -15 by 3 and you get x= -5

Answer 6

x = -5

Answer 7

Well, Algebra 1 is a Freshman class

First you use distributive property so it would turn out to be...

((-5)+25x)-(40x-10) = -12x

-15-15x =-12x

     +15x  +15x

-15 = 3x

/3       /3

x= -5
