SOLUTION: I think i know the answer to the problem, but would like to know how to check it. Maybe you can help. 4(5-2b)+3(2b-10)=7(b+2) breakdown: 20-8b+6b-30=7b+14 14b+50=7

Question 76843: I think i know the answer to the problem, but would like to know how to check it. Maybe you can help.
4(5-2b)+3(2b-10)=7(b+2)
breakdown: 20-8b+6b-30=7b+14
14b+50=7b+14
-7b -7b
7b+50=14
-50 -50
7b/7=-36/7
Distributive property, combine like terms, -50 from both sides. Check this and send me the breakdown check solution. Thank you.

4(5-2b)+3(2b-10)=7(b+2)
breakdown: 20-8b+6b-30=7b+14
14b+50=7b+14 <---here are your mistakes -8b+6b=-2b not 14b. 20-30=-10
-7b -7b
7b+50=14
-50 -50
7b/7=-36/7

:
Check by letting b=-8/3 and see if the sides equal

We're right!!!
Happy Calculating!!!
