URGENT ! HELP ! Question is in photo below.

kifflom [539]

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

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"
