Question 14512
{{{2/3}}}n-11=4+n
First get the variable on the same side, subtract both sides by n;
{{{2/3}}}n-11-n=4+n-n
{{{-1/3}}}n-11=4
now add 11 to both sodes;
{{{-1/3}}}n-11+11=4+11
{{{-1/3}}}n=15
Now multiply both sides by the inverse of {{{-1/3}}}which is {{{-3/1}}};
{{{-1/3}}}n({{{-3/1}}})=15({{{-3/1}}})
n=-45
Now check your answer;
{{{2/3}}}(-45)-11=4+-45
{{{-90/3}}}-11=-41
-30-11=-41
-41=-41
Checks out!!!
Hope you understand
