## anonymous one year ago Medal and fan ASAP |2x-1|-4=3

1. anonymous

help me understand?

2. pooja195

add the 4 to both sides

3. pooja195

That way it will be easier to solve this and we can isolate the statement from any numbers out of the bars

4. anonymous

|2x-1|=7

5. anonymous

then?

6. pooja195

now set up 2 equations... do you know what the equations would look like/

7. anonymous

no?

8. pooja195

We know either $\huge ~\rm~2x−1=7 ~~~~~~or ~~~~~~2x−1=−7$

9. anonymous

ok.. next?

10. pooja195

solve and you will end up with TWO solutuions

11. anonymous

how? Its just absolute value? the answer is always positive...

12. anonymous

i just need step by step how to

13. anonymous

next???

14. pooja195

We need to solve the equations now. We set up to equations to show that $\huge~\rm~|2x-1|$ either equations positive 7 or negative 7

15. anonymous

ok.. next?

16. pooja195

We know either $\huge ~\rm~2x−1=7 ~~~~~~or ~~~~~~2x−1=−7$

17. anonymous

ok.. next

18. pooja195

solve

19. anonymous

x=-3 or x=4

20. anonymous

|2x-1|+4=3

21. anonymous

2x-1=-1 ??

22. anonymous

not solvable!!?

23. pooja195

$$\color{blue}{\text{Originally Posted by}}$$ @Adrianna765 x=-3 or x=4 $$\color{blue}{\text{End of Quote}}$$ this is right

24. anonymous

ok.. thanks!!!
