Question 352000
marrianne figured out that her father's age is her age plus five to the power
 of four, less 365, minus 22, all divided by six. if her father is 42,
 how old is marrianne?
:
Let m = her age
:
Write what it says:
"father's age is her age plus five to the power of four, less 365, minus 22, all divided by six."
42 = {{{((m + 5^4 - 365 - 22))/6}}}
which is
42 = {{{((m + 625 - 387))/6}}}
42 = {{{((m + 238))/6}}}
Multiply both sides by 6 and rearrange
m + 238 = 6(42)
m = 252 - 238
m = 14 yrs old is M's age

You can check solution, substitute 14 for m in the original equation and see if you get 42
