-(-5q-3.1r+4.5) equivalent expression without parenthesis
mote1985 [20]

The equivalent expression of -(-5q-3.1r+4.5) without parenthesis is 5q + 3.1r - 4.5

In order to get the equivalent expression without parenthesis, we will use the distributive law. Also, we must know that:

  • - × - =+
  • + × - = -
  • + × + =+

Given the expression -(-5q-3.1r+4.5)

This can also be written as -1 (-5q-3.1r+4.5)

On expansion

-1 (-5q-3.1r+4.5)

= -1(-5q) -1(-3.1t) -1(+4.5)

Using the sign rule, the result becomes:

= 5q + 3.1r - 4.5

Hence the equivalent expression without parenthesis is 5q + 3.1r - 4.5
