How do you solve 3(x−4)=15?

3(x − 4) = 15

divide both side by 3

x - 4 = 5

x = 5 + 4

x = 9

----------------

check

3(9 - 4) = 15

9 - 4 = 5

5 = 5

the answer is good

Answer:

9

Explanation:

3(x-4)=15

Use distributive property with the 3 (multiply 3 times x and 3 times -4)

3x-12=15

Add the 12 to both sides.

3x=27

divide 27 by 3.

x=9
