**Solving**

**one step equations**

solve by

**inspection**15+b=23

**Isolate**the variable

15+(-15)b=23-15

We do 23-15 and that will give you

**B**n=8

Now

**varify**your answer15+b=23

15+8=23

23=23

**^ MAKE SURE YOU DO THIS!**

solving with

**algebra tiles**.**1 Step equations**

3) 15+b=23

15+8=23

15) V/8=2

V/8x8=2x8

V=16

V/8=2

16/8=2

2=2

**2 Step equation**

3) 9x-7=-7

9x-7+7=-7+7

9x=0

9x/9=0/9=0

0=0

9x-7=-7

9(0)-7=-7

-7=-7
