5b - 4 = 2b + 17

subtract 2b from both sides

3b - 4 = 17

add 4 to both sides

3b = 21

divide both sides by 3

b = 7


answer

b = 7

Hey!


Here is the equation:


[tex] 5b - 4 = 2b + 17 [/tex]


Add 4 to leave 5b by itself. It becomes:


[tex] 5b = 2b + 21 [/tex]


Subtract 5b from 2b to leave only 1 variable. It becomes:


[tex] 3b = 21 [/tex]


Divide by 3 to leave b by itself


[tex] \frac{3b}{3} = \frac{21}{3} [/tex]


It becomes:


[tex] \framebox{b = 7} [/tex]
