Solving Equations by using Addition/ Subtraction: One sided equations

$5b+2b-7+14=0$

$b=?$

It's important to remember that when we have regular numbers and unknowns, we cannot add or subtract them directly.

Let's collect like terms:

5b+2b-7+14=0

7b+7 = 0

Let's move terms

7b = -7

Let's divide by 7

b=-1

And that's the solution!
