find A Number Such That Seven Times 1 Less Than Twice The Number Is The Same As 5 More Than 10 Times The Number.
:
Let n = "a number"
:
Write what it says, place the equal sign where it says,"is the same as"
7(2n-1) = 10n + 5
14n - 7 = 10n + 5
14n - 10n = 5 + 7
4n = 12
n =
n = 3
:
:
Check this, substitute 3 for n in the original statement
"A Number Such That Seven Times 1 Less Than Twice The Number Is The Same As 5 More Than 10 Times The Number."
7(2(3) - 1) = 10(3) + 5
7(6-1) = 30 + 5; confirms our solution of n=3
