Question 106285
let two comsecutive even be: {{{x}}} and {{{x+2}}} where {{{x+2}}} is greater number

if the greater of two comsecutive even integers {{{x+2}}} is {{{20}}} more than twice the smaller ({{{2x}}}), then we have:

{{{2x + 20 = x + 2}}}  ......... add {{{-x}}} to both sides

{{{2x - x + 20 = x - x + 2}}}

{{{x + 20 = 2}}}...........add {{{-20}}} to both sides

{{{x + 20 - 20 = 2 - 20}}}


{{{x = -18}}}............smaller number

{{{x+2 = -18+2 = -16}}}.......greater number

check:

{{{2x+20}}} must be equal {{{-16}}}

{{{2*(-18) + 20 = -36 + 20 = - 16}}}
