Solving 2 step equations

Two step equations have addition or subtraction and multiply or divide 3x + 1 = 10 3x + 1 = 10 4y + 2 = 10 4y + 2 = 10 2b + 5 = 9 2b + 5 = 9 2x - 1 = 5 2x - 1 = 5 3x + 5 = 2 3x + 5 = 2

Let’s look at 2x + 2 = 6 First subtract 2 from both sides First subtract 2 from both sides 2x + 2 -2 = 6-2 2x + 2 -2 = 6-2 2x = 4 2x = 4 Then divide both sides by 2 Then divide both sides by 2 2x/2 = 4/2 2x/2 = 4/2 So x=2 So x=2

How about 3x + 2 = 14 First subtract 2 from both sides First subtract 2 from both sides 3x + 2 - 2 = 14 - 2 3x + 2 - 2 = 14 - 2 Which gives you 3x = 12 Which gives you 3x = 12 Then divide both sides by 3 Then divide both sides by 3 3x/3 = 12/3 3x/3 = 12/3 So x = 4 So x = 4

Let’s try 4x - 1 = 3 Add 1 to both sides Add 1 to both sides 4x - 1 + 1 = 3 + 1 4x - 1 + 1 = 3 + 1 4x = 4 4x = 4 Then divide both sides by 4 Then divide both sides by 4 4x/4 = 4/4 4x/4 = 4/4 So x = 1 So x = 1

Try these on your own 3x + 1 = 10 3x + 1 = 10 4y + 2 = 10 4y + 2 = 10 2b + 5 = 9 2b + 5 = 9 2x - 1 = 5 2x - 1 = 5 3x + 5 = 2 3x + 5 = 2 X = 3 Y = 2 B = 2 X = 3 X = -1
