HELP US PLEASE!! Daughter is in Middle School and studing Algebra. Question relates to intergers and using like terms to solve equations??? (and I attended collage- WOW I feel old and under educated) But can't recall basic info needed to solve this one.
Here you go:
10B +19 = 4B - 5
can anyone give answer and possibaly explain for daughter and myself how to colve these types of problems for future reference.
Thanks in advance.

Combine like terms. terms are separated by + and - signs.
The types of terms here are variables (with B) and constants (just numbers - never change value).
Get like term on the same side.
What you do to one side, you do to the other.
Subtract 4B from both sides.
6B + 19 = -5
Subtract 19 from both sides.
6B = -24
Divide by 6
B = -4

(1) Make sure variable terms, i.e. the B terms, are on one side of the equation and the number terms are on the other. That means...
(a) Subtract 4B from both sides.
10B + 19 - 4B = 4B - 5 - 4B
6B + 19 = -5
(b) Subtract 19 from both sides.
6B + 19 - 19 = -5 - 19
6B = -24
(2) Isolate the variable. This means dividing 6 by both sides
6B/6 = -24/6
B = -4

1. put similar variables on one side (subtraction or addition)
- subtract 4B from 10B
- subtract 19 from -5
10B + 19 = 4B - 5
6B = -24
2. then do multiplication or division leaving the variable on
one side and the numbers on the other
- divide 6 from -24
24/6 = 4
3.there is your answer
- B = -4 (because of the negative sign from #2, and until
dividing by another negative, it follows)
i hope this helps
good luck to your daughter and you

First group the like terms;
10B + 19 = 4B - 5
In order to do this, subtract the same term from both sides of the equation.
10B - 4B + 19 = 4B - 4B -5
which gives
6B + 19 = -5
then subtract 19 from both sides
6B + 19 - 19 = -5 -19
which gives
6B = -24
now divide both sides of the equation by the cofactor of B
6B/6 = -24/6
which gives
B = -4

subtract 4B on each side and that would be 6B+19= - 5. Then subatract 19 from each side. then u get 6B= -24. Then divide each number by 6 and b= - 4. It's that easy.
Answer: b= - 4

10B +19 = 4B - 5
10B + 19 -4B = 4B - 5 -4B
6B + 19 = -5
6B + 19 - 19 = -5 -19
6B = -24
6B / 6 = -24/6
B = --4
That's the very step-step explanation format. Here's usual format.
10B +19 = 4B - 5
10B -4B = - 5 -19
6B = -24
6B = -4

10B+19=4B-5
The key is to get like terms on both side of the equation together.
10B+19-19=4B-5-19
Whatever you do one side of the equation ,you must do on the other side
10B=4B-24
10B-4B=4B-4B-24
6B=-24
Simplify as much as possible
6B/6=-24/6
B=-4

Terms from an equation can change sides, changing signs.
Terms "+" at one side, goes to the other side "-"
Terms "-" at one side, goes to the other side "+"
Terms "x" at one side, goes to the other side "/"
Terms "/" at one side, goes to the other side "x"
So:
10B + 19 = 4B - 5 = 10B - 4B = - 5 - 19
6B = - 24
B = - 24 / 6 = -4

10B +19 = 4B - 5
subtract 4B from each side:
6B+19=-5
subtract 19 from each side:
6B=-24
B= -4

10B+19=4B-5 at this relation we( - )19 and 4B so
10B-4B+19-19=4B-4B-5-19
6B+0=0-24
6B=-24
B=-24/6
B=-4
