How would you go about to solve these inequalties ?

Question

2x+3(5x-7)=13

3(x+4)+2(x=14)=180

7x+5+5x+1=90

-7=(2/3)(-6)+b.

Please do not use websites and list your answers step by step.

Thank you.

Answer 1

2x + 15x-21= 13 ( i multiplyed 5x and - 7 by 3 and remove the brackets).

17x = 13+21

17x = 33

x = 33/17.

use the same judgement for all of the equations.

first u remove the brackets, keeping in mind the operations order, then separete the numbers constants from the variables ( the ones containing x).  then simplify.  

Answer 2

Firstly there is no inequality in the question... maybe you meant solve these equations

2x+3(5x-7)=13

2x+15x-21=13

17x=34

x=2

3(x+4)+2(x=14)=180

Typing error here...

7x+5+5x+1=90

12x+6=90

12x=84

x=7

-7=(2/3)(-6)+b

-7=-4+b

b=-3

Answer 3

i have no clue
