Answer:

\huge\boxed{\boxed{\bf\:4r + 11}}

Step-by-step explanation:

Given,

  • C = r + 7
  • D = - 2r + 3

We need to find the value of 2C - D. To solve this, we need to substitute the values of C & D in the expression.  So,

\tt\:2\:C - D\\\\\sf\:{Substitute \: the \: given \: values}\\\\\tt\:= 2(r + 7) - (-2r + 3)\\\\\sf\:Now, \: follow \: the \: distributive \:property\\\\\tt\:= 2r + 14 + 2r - 3\\\\\sf\:Rearrange\:the\:terms\\\\\tt\:= 2r + 2r + 14 - 3\\\\\sf\:Do \: the \: required \:arithmetic \: operations\\\\=\boxed{ \bf\:4r + 11}

\rule{200}{2}

  • The answer will be <u>4r + 11 </u> in the standard form.

\rule{200}{2}

Hope this helps!
