    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?

    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 = ?

    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?

    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?

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