\frac{3(x+5)}{2} \cdot 2=21\cdot 2

Above step we use "Multiplication property of equality"

3(x+5)=42

In the above step we "Simplify on both sides of equation"

3x+15 = 42

In the above step we use "Distribution property"

3x+15-15=42-15

The above step is the result of using "Subtraction property of equality"

3x=27

Above step is result of "Combining the like terms"

\frac{3x}{3} =\frac{27}{3}

Above step is the result of using "Division property of equality"

x=9

Above step is result of "Simplifying fractions on either side of equation"

poizon [28]
Yes they do. In order to do this you must make the fraction 70/2 and 105/3. If you divided each one of those you get 35 for both which means it's a proportion.
