Question 473529


{{{-10=-14v+14v}}}.... .this equation you need to solve for {{{v}}}


{{{-10=highlight(-14v+14v)}}}...since you have {{{-14v}}} and {{{-14v}}}, their sum is equal to {{{zero}}}; so, there is {{{NO}}} solution
    
                 
{{{a-2+3=-2}}}....this equation you need to solve for {{{a}}}

{{{a-2+3=-2}}}...cancel {{{-2}}} on both sides

{{{a-cross(2)+3=-cross(2)}}}

{{{a+3=0}}}..add {{{-3}}} to both sides

{{{a+3-3=0-3}}}

{{{highlight(a=-3)}}}.solution
