OpenStudy (anonymous):

check ur answer, u know how u solve the problem n then check it right

OpenStudy (anonymous):

b=39/7

OpenStudy (anonymous):

right?

OpenStudy (anonymous):

It's right but u have to show that ur answer is right

OpenStudy (anonymous):

how u got

OpenStudy (anonymous):

b-9+6b=30 7b-9=30 7b-9+9=30+9 7b=39 b=39/7

OpenStudy (anonymous):

got it?

OpenStudy (anonymous):

Yeah it's 39/7 http://www.wolframalpha.com/input/?i=+b-9%2B6b%3D30

OpenStudy (anonymous):

because you combine like terms, b and 6b are like terms so add them 7b - 9 = 30 Now the goal is to get the b by itself, so add 9 to both sides 7b = 39 Now the opposite of multiplication is division, so you want to divide both sides by 7 to get b by itself b = 39/7 it's left as a fraction because you can't really divide it evenly

the answer is correct, but simplify 39/7!! Udon't get watt I'm saying the answer is correct

OpenStudy (anonymous):

well you can turn it into a decimal, but it's not pretty. 39/7 is simplified enough

example: if my answer is 4 n my problemwas 5=5M-23+ 2m to make sure my answer is correct Il do it this way!! 5=5[4]-23+2[4] 5=20-23+8 5=-3+8 5=5 True this is wat I mean now do this with the first problem!!
