the answer is x=8
here is how it works
3(x-5)=9
simplify
3(x)-3(5)=9
3x-15=9
then add 15 to each side
3x=24
divide each side by 3
x=8
Good Luck!!!

3(x-5) = 9
// divide by three first....' Order of Operations'
(x-5) = 3
// add 5 to both sides
x=8

3 times x = 3x
3 times -5 = -15
So now you have:
3x - 15 = 9
Now isolate x
First, add 15 to both sides
3x - 15 + 15 = 9 + 15
3x = 24
Then, divide both sides by 3
3x/3 = 24/3
x = 8

3(x-5)=9
divide 3 for both sides
x-5 = 3
add 5 for both sides
x = 8

3(X-5)=9
3x-15=9 (Distribute 3)
3x=9+15 (Transpose 15)
3x=24
3x/3=24/3 (Divide both sides by 3)
x=8!!!!!

3(x-5)=9
3x - (3*5) = 9
15+ (3x-15)=9+15
3x=24
3x/3=24/3
x=8

use the distributive property:
3x-15=9
add fifteen to each side:
3x=24
divide by three:
x=8
