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
