solve the equation.
show work
check answer

Answer 1

I just showed you how to do the same thing before! Have a try!
All you have to do is group the like terms together until you have b on the left and a numerical value on the right.

Answer 2

so wait subtract 8b from 3b?
then drop down the answer and the 9 and what it eaquals to then subtract nine from both sides

Answer 3

correct so step it out and I'll check it for you

Answer 4

3b-9-8b=11
5b-9=11
+9 +9
-----------
14b=18
14/14=0
18/14=

Answer 5

Not correct but nice try!
3b-8b=-5b not +5b
Also when you add 9 to both sides, 9 cant be added to 5b as it has a b in it.
so +9 on the left hand side just deletes the -9 (as -9+9=0)
+9 on the right hand side is 11+9=20 so go back through and see how you go

Answer 6

wait where do i start?

Answer 7

3b-9-8b=11
collect like terms first on the left hand side, then just try and get b on left side and numeric value on right side following the rules I gave you above. You were on the right track before, you just werent calculating correctly.

Answer 8

3b-9-8b=11
8b-3b= -5b
-5b-9=11
-5b/5=0
11/5=2.2

Answer 9

No your getting confused look how I step it out and you should get what I mean
3b-9-8b=11
ok first lets group the b values together
3b-8b-9=11
-5b-9=11
Then I need to get rid of the -9 on the left hand side so I +9 to both sides. Remember you can only +9 to numeric values, not any with a b term in it.
-5b-9(+9)=11(+9)
-5b=20
Then I need to get the -5 over to the other side, so I divide both sides by -5
-5b/5=-20/5
b=-4

Answer 10

how do i check this one

Answer 11

????

Answer 12

same as before just replace -4 for x in the original problem

Answer 17

yes

Answer 18

work out for you?
