Answer:
Explanation:
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
9
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
