What is the answer to this equation? : 6 (1R + 5) + 3R =

The answer to this equation is 15R.

Use distributive property to remove the parenthesis. Distributive property allows us to "distribute" or share the one outside the parenthesis to all term inside the parenthesis.

6 (1R + 5) + 3R

= 6 * 1R + 6 * 5 + 3R

Then work on the multiplication

= 6 * 1R + 6 * 5 + 3R

= 6R + 30 + 3R

Add the one with variable R together

= 6R + 30 + 3R

= 9R + 30

This is the simplest expression
