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
I have 10 more questions is that ok
Yeah sure....I'm about to sign off inna few mins but anyone else can see this so they'll be able to help
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
will it be 8x-6
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
+15 i mean
Good work! So now we have: 3x - 9 = 5x + 15 Now subtract 3x from both sides. Can you do that?
luhm i get lost right here can u help me please
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?
5x - 3x = ?x
i got 17 = x if i skip ahead will tht be correct
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 :)
15 minus 9 is -24
Well -15 - 9 = -24 sure enough. So we have -24 = 2x And x = -24/2 = ?
Correct. The solution is x = -12.
thanks dude i appreciate your help
