Correct Question : $\rm{Add\:\left(\:3a\:-\:2b\:+\:c\:+\:3\right)\:+\left(a\:+\:3b\:-\:20\:-\:4\right)}$

Solution :

Given to Add $\rm{\left(\:3a\:-\:2b\:+\:c\:+\:3\right)}$ and $\rm{\left(a\:+\:3b\:-\:20\:-\:4\right)}$

• Remove Parenthesis

$\rm{=3a-2b+c+3+a+3b-20-4}$

• Group Like Terms

$\rm{=3a+a-2b+3b+c+3-20-4}$

$\rm{=4a-2b+3b+c+3-20-4}$

$\rm{=4a+b+c+3-20-4}$

$\rm{=4a+b+c-21}$
