Question

Choose the property for each

Answer 1

w = 12

Explanation:

Simplifying equation:

To simplify the equation, we have to isolate 'w'. To isolate 'w',

• Add 21 to both sides of the equation.
• Multiply both sides by 2.

`(w)/(2)-21=-15\\\\\\(w)/(2 )-21+21=-15+21 \ \text{\bf (Addition property of equality)}\\`

`(w)/(2)= 6`

`2*(w)/(2)=6*2 \ \text{\bf (Multiplication property of equality)}\\\\\\`

w = 12
