Answer:

 In step 1 subtraction property is used and in step 2 division property is used.

Explanation:

 We have the equation   2x + 6 = 22

Step 1

  The subtraction property of equality tells us that subtracting the same number to each side of an equation gives us an equivalent equation

    So subtracting 6 from both sides

               2x + 6 - 6 = 22 - 6

                    2x = 16

Step 2

   The division property of equality tells us that you can divide each side of an equation with the same nonzero number to produce an equivalent equation

     So dividing each side by 2.

                [tex]\frac{2x}{2} =\frac{16}{2} \\ \\ x=8[/tex]

Answer:

Given an equation: 2x+6=22

Step 1: Using Subtraction property of equality:

For all real numbers a, b, and c. If a=b then a-c=b-c

If two expressions are equal to each other and you subtract the same value to both sides of the equation, the equation will remain equal.

Now, using above property we have ,

[tex]2x+6=22[/tex]

[tex]2x+6-6=22-6[/tex]

Simplify, we get:

[tex]2x=16[/tex]

Step 2: Using division property of equality:

For any numbers a, b, c with c≠0.

If a=b, then [tex]\frac{a}{c}= \frac{b}{c}[/tex]

[tex]\frac{2x}{2}=\frac{16}{2}[/tex]

Simplify we get;

x=8
