2) 3x-5=10
You add 5 on both sides, so that the fives cancels.
3x-5=10
+5 +5
That leaves you with
3x=15
Then you have to get the x alone. You divide the three on both sides.
3x/3=15/3
The threes cancel out, so you now have
x=5
3) x
— -4=14
3
On this one you need to add 4 on both sides to cancel it out.
+4 +4
Since you just canceled the 4’s out that makes the equation...
X
— =18
3
Now you want to get x alone so you have to find a way to cancel the threes out. You times the three to the x/3.
3 X
— =18
3
What you do to one side you have to do to the other.
3 X
— =18x3
3
That leaves you with...
X=54
Hope this helped. Sorry if I’m late
