Answer:
[tex]10x + 5y - 15z[/tex]
Step-by-step explanation:
[tex]5(2x + y - 3z)[/tex]
To get the equivalent expression we apply distributive property
a(x+b)= ax+ab
Using distributive property we distribute the number inside the parenthesis  Distribute 5 inside the parenthesis
5 times 2x becomes 10x
5 times y becomes 5y
5 times -3z becomes -15z
[tex]5(2x + y - 3z)[/tex]
[tex]10x + 5y - 15z[/tex]
