Answer:

b = 7

Step-by-step explanation:

3b - 4 = 17 is 7 because you are trying to isolate the variable. First, you add 4 to each side (17 + 4 and 4 + 4). Since, 17 + 4 is 21, 3b = 21. Now, since the inverse operation of multiplication is division, we divide 3 by both sides. 17 divided by 3 is 7. So b = 7.

Answer:

3b−4=17

Answer:

b=7

Step-by-step explanation:

3b−4=17 : b=7

STEPS

3b-4=17

Add 4 to both sides

3b - 4 +4 = 17 + 4

Simplify

36 = 21

Divide both sides by 3

3b/3 = 21/3

Simplify

b=7
