what do u mean

3. Suckatmath94

4. tishara429

no

5. tishara429

can u tye it in steps

6. tishara429

can u type it in steps

7. agustin_pc

if x = -4 9-2(4(-4)+5) 9-2(-16+5) 9-2(-11) 9+22 31

8. tishara429

can u do it all together thev whole promble

9. Trexy

just replace the x to 9-2(4x+5) so it will be 9-2 (4(-4)+5) like @agustin_pc put..

10. Trexy

and do the first paranthesis..

11. Trexy

12. tishara429

\[-7x-3(9-7x) if x=-2\]

13. tishara429

help

14. Trexy

same thing sine the x is given just replace the x to -2

15. tishara429

can u type the promble in steps please

16. agustin_pc

-7(-2)-3(9-7(-2))

17. Trexy

−7x−3(9−7x)ifx=−2 since x is given, we replace the x to -2 -7(-2)-3(9-7(-2)) and we follow the PEMDAS which is parentheses first right, so -7(-2)-3(23) and same thing again -7(-2) is 14 -3(23) is -69 so its 14-69 and u finish it.. and i think thats how you do it.. or someone can check mine and if something is wrong just recheck it and thankz

18. Trexy

when it comes to parentheses for me I used my TI-84 because its easy for me.. you can do it in the paper and if your not sure I use calculator.. so yeah

19. Trexy

did you get it? hope u understand

20. tishara429

6(3x-1)-10x if x=7

21. Trexy

really??

22. Trexy

you do it first replace the x to -7 when you replace it put parentheses on it so u dont get confused

23. Trexy

tell me if did and we go to the next round

24. agustin_pc

if x =7 -> 6(3(7)-1)-10(7), 6(21-1)-70, 6(20)-70, 120-70 = 50

25. Trexy

he got it ^

26. tishara429

7-4x+2(5x+8) if x=-2

27. Trexy

Ma'am do u know how to do it?
