5-8b+6-2B=61
Combine like terms:
-8b - 2b = 61 - 5 - 6
-10b = 50
b = -5
Follow this pattern to solve the other problems. We'll be glad to check your answers.
for #2 i keep getting the answer -4.5 and i check and its wrong this is what i did
4x-8x=-4x
6-9=-3
-4x--3=21
18=21
x=-4.5
are the steps i did wrong and when i plug in the number i get 3 as an answer instead of 21
and i did the steps u did for all problems and i check and get a wrong answer
As a non-mathematician, I get confused by a lot of numbers, too. <g> But here's the way to do 2.
4x-6-8x-9=21
-4x - 6 - 9 = 21
-4x = 21 + 15
x = -9
The answer for number 3 is 3. Can you keep working this problem until you get the right answer?
#3 was easy and # 4
i keep getting the wrong answer which is 3/8
My answer for 4 is 4.5
When you do the problem or the proof, please be sure you don't leave out any parts of the original problem. (I kept leaving a part of the original problem out until I went back and triple checked.)
