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

1. anonymous

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

2. anonymous

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

3. anonymous

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. anonymous

ok

5. anonymous

thanks for helping me with this..

6. anonymous

first you subtract -3 both sides

7. anonymous

so i - 3 from 4x and 3

8. anonymous

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

9. anonymous

then you have 4x < 32

10. anonymous

4x<32

11. anonymous

x=8

12. anonymous

yeah good then you dont need 4 there

13. anonymous

excellent

14. anonymous

x<8

15. anonymous

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

16. anonymous

how would you write x<8 in interval notation

17. anonymous

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

18. anonymous

|dw:1353884676497:dw|

19. anonymous

thats how you write x<8 in interval notation above

20. anonymous

yes thats the interval

21. anonymous

22. anonymous

thank you so much

23. anonymous

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

24. anonymous

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

25. anonymous

do i hve too hve a - in there
