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

yes please
OpenStudy (kropot72):
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?
OpenStudy (anonymous):
yes 3x- 9 = 5x - 15
OpenStudy (anonymous):
+15 i mean
OpenStudy (kropot72):
Good work! So now we have:
3x - 9 = 5x + 15
Now subtract 3x from both sides. Can you do that?
