Question 1152062


let a number be {{{x}}}
the sum of a number and two: {{{x+2}}}
 multiplied by four: {{{(x+2)4}}}
equals twenty-three, plus the number: {{{(x+2)4=23+x}}}

now, you can solve for {{{x}}} and find out what that number is:

{{{(x+2)4=23+x}}}
{{{4x+8=23+x}}}
{{{4x-x=23-8}}}
{{{3x=15}}}
{{{x=5}}}-> that number is {{{5}}}

check:

{{{(x+2)4=23+x}}}
{{{(5+2)4=23+5}}}
{{{(7)4=28}}}
{{{28=28}}}
