Question 420017
Since 7 days = 1 week, you can multiply both sides by {{{21x^2-14x}}} to get



{{{7(21x^2-14x)}}} days = {{{1(21x^2-14x)}}} weeks



Now isolate {{{21x^2-14x}}} by dividing both sides by 7 to get



{{{21x^2-14x}}} days = {{{1(21x^2-14x)/7}}} weeks



{{{21x^2-14x}}} days = {{{3x^2-2x}}} weeks



So {{{21x^2-14x}}} days = {{{3x^2-2x}}} weeks
