so you add 4 to both sides....now you have x/3 = 15 multiply both sides by 3 which leave x = 45 now check....45/3? is 15... 4 = 11 so yes

Okay so combine like terms 2x  4x = 2x 1  9 = 8 so we have 2x  8 =12 now add 8 to both sides 2x = 20 x = 10

3(x  3) = 5(x + 3) First remove the brackets on each side by multiplying each term inside the brackets by the term outside the brackets. Can you do that?

yes 3x 9 = 5x  15

kropot72Best ResponseYou've already chosen the best response.0
Good work! So now we have: 3x  9 = 5x + 15 Now subtract 3x from both sides. Can you do that?

What is the result of subtracting 3x from 3x; 3x  3x = ?
 one year ago

kropot72Best ResponseYou've already chosen the best response.0
Correct! So now when we subtract 3x from both sides of 3x  9 = 5x + 15 we get 9 = 5x  3x + 15 What happens to the right hand side when you combine the two terms in x?

i got 17 = x if i skip ahead will tht be correct

kropot72Best ResponseYou've already chosen the best response.0
Correct again! Our equation has now become 9 = 2x + 15 Next step is to subtract 15 from both sides to get the term in x all by itself on the right hand side. Can you do that?

Sorry x = 17 is not correct. Please continue with the method I am showing you :)

Well 15  9 = 24 sure enough. So we have 24 = 2x And x = 24/2 = ?

kropot72Best ResponseYou've already chosen the best response.0
Correct. The solution is x = 12.
