Given the equation: 5b = 19
we will select all the equations below that are equivalent to the given
the first equation:

So, the first equation is correct
The second equation: 5b - 17 = 2 ⇒ 5b = 19
So, the equation is correct
The third equation: 5b - 11 = 8 ⇒ 5b = 19
So, the equation is correct
The fourth equation: 5b - 12 = 8 ⇒ 5b = 20
So, the equation is wrong
So, the answer will be: select the following equations:
5b - 3 = 16
5b - 11 = 8
