five is equal to twenty more than twice the number. Not sure if my
translation is correct. 8(4n)+5=20+2n
>>...Eight times the difference between four times a number and five
is equal to twenty more than twice the number...<<
Replace the words "a number" and "the number" by n, so we now have:
>>...Eight times the difference between four times n and five is equal
to twenty more than twice n...<<
>>...Eight times the difference between four times n and five is equal
to twenty more than twice n...<<
Replace the words "four times n" by "4n" and "twice n" by "2n", so we
now have:
>>...Eight times the difference between 4n and five is equal
to twenty more than 2n...<<
>>...Eight times the difference between 4n and five is equal
to twenty more than 2n...<<
Replace the words "the difference between 4n and five" by "4n-5" and
"twenty more than 2n" by "2n+20", so we now have:
>>...Eight times 4n-5 is equal to 2n+20...<<
>>...Eight times 4n-5 is equal to 2n+20...<<
Replace the words "Eight times 4n-5" by "8(4n-5)" and
"is equal to" by "=", so we now have:
>>...8(4n-5) = 2n+20...<<
8(4n-5) = 2n+20
Solve that and get
n = 2
