Respuesta :
remmeber you can do anything to an equation as long as you do it to both sides
divide both sides by 6
b-5=2
add 5 to both sides
b=7
divide both sides by 6
b-5=2
add 5 to both sides
b=7
6(b-5) = 12
multiply six with both numbers in brackets.
6b-30=12
6b = 12 + 30
-30 became +30 because it was moved to other side of equal sign.
so.....6b = 42
b=42/6 = 7
SO THE ANSWER WILL BE........D.
GLAD TO HELP ! :)
