Question 640765


1) is {{{x=3}}} a solution for {{{4x+1=-11}}}?

let's solve this tor {{{x}}}: {{{4x+1=-11}}}

{{{4x=-11-1}}}

{{{4x=-12}}}

{{{x=-12/4}}}

{{{x=-3}}}......so, the answer is {{{x=3}}} is NOT a solution for {{{4x+1=-11}}}


2)  solve using the addition principle   {{{p+2=-5}}}

{{{p+2-2=-5-2}}}

{{{p+cross(2)-cross(2)=-5-2}}}

{{{p=-7}}}
