## MauriceLong Group Title Use both the addition and the multiplication propeties of inequalitiy to solve the inequality 4x+3<35 2 years ago 2 years ago

1. gvt016

Use the same properties as an equation, the difference is the answer

2. MauriceLong

Im confuse with this problem can u explain how too do this problem please

3. gvt016

Well I know that you need a complete explanatio but there are people on this site sayimg that the students shouldn´t get complete answers I will anyway......

4. MauriceLong

ok

5. MauriceLong

thanks for helping me with this..

6. gvt016

first you subtract -3 both sides

7. MauriceLong

so i - 3 from 4x and 3

8. gvt016

this way 4x + 3 - 3 < 35 -3

9. gvt016

then you have 4x < 32

10. MauriceLong

4x<32

11. MauriceLong

x=8

12. gvt016

yeah good then you dont need 4 there

13. gvt016

excellent

14. MauriceLong

x<8

15. gvt016

that means all the numbers before 8 ..................

16. MauriceLong

how would you write x<8 in interval notation

17. gvt016

on equations the answer is one number on inequalities the answers are many numbers

18. gvt016

|dw:1353884676497:dw|

19. MauriceLong

thats how you write x<8 in interval notation above

20. gvt016

yes thats the interval

21. gvt016

22. MauriceLong

thank you so much

23. MauriceLong

can i write it like this (-$(\infty;8) or <\infty;8>$

24. gvt016

Yeah both are correct, just add (-) sign before the infinite symbol

25. MauriceLong

do i hve too hve a - in there
