solve 5(2x – 3) = 5

OpenStudy (anonymous):

5(2(2)-3) = 5 x = 2

OpenStudy (anonymous):

thank u so much i needed that

OpenStudy (anonymous):

no problem u have any other questions u need help with

OpenStudy (anonymous):

yes i do omg your so helpful

OpenStudy (anonymous):

ok here's one

OpenStudy (anonymous):

4(x – 8) = 4

OpenStudy (anonymous):

explain to me how you solve it

OpenStudy (anonymous):

well i use mental math really

OpenStudy (anonymous):

im just not good at math at all

OpenStudy (anonymous):

think what times what = 4

OpenStudy (anonymous):

i mean 4 *x = 4

OpenStudy (anonymous):

so it would be 2 right cuz 2 * 2 = 4

OpenStudy (anonymous):

no u have to think since 4's factors are 1,2,4 (1*4 is 4) so (8-7 =1) and 1*4 = 4

OpenStudy (anonymous):

oooooooooooo i get what your saying

OpenStudy (anonymous):

k so what is x

OpenStudy (anonymous):

idk 4 i think

OpenStudy (anonymous):

is the answer x=1

OpenStudy (anonymous):

no if 8-7 = 1 and 1*4 = 4 so x = 7 do u get it

OpenStudy (anonymous):

so its x=2

OpenStudy (anonymous):

if not i dont get it at all

OpenStudy (anonymous):

u know what i know that wrong

OpenStudy (anonymous):

the answer is x = 7 try it

OpenStudy (anonymous):

u r really nice for taking the time to help me i don't really get that a lot

OpenStudy (anonymous):

well i try it and that was not right

OpenStudy (anonymous):

my bad its 9 i hope u didnt put the answer in yet

OpenStudy (anonymous):

no i did not

OpenStudy (anonymous):

great yh x = 9

OpenStudy (anonymous):

ok thats the one

OpenStudy (anonymous):

any more

OpenStudy (anonymous):

u dont mind do u

OpenStudy (anonymous):

no not rlly

OpenStudy (anonymous):

dang u most not b doing anything well kk

a = 4 and b= 1

OpenStudy (anonymous):

its hard right

OpenStudy (anonymous):

idk is that the question

OpenStudy (anonymous):

yup looks it

OpenStudy (anonymous):

how about this Which inequality has the solution z < -4? z + 4 < 0 z – 4 < 0 z + 3 < 1 z – 3 < 1

OpenStudy (anonymous):

well honestly inequalities are not my fav sub subject but i would have to say z + 3<1

OpenStudy (anonymous):

well u solved most right whats wrong now

OpenStudy (anonymous):

inequalities are not my fav sub subject i just told u

OpenStudy (anonymous):

I have a big test an i dont know most of it in the 8th grade math is not my favorite
