Question 157557
Let {{{x}}} = Maria' age
{{{x+2}}} = Xul's age
condition: {{{x+x+2>32}}}, sum is over 32 years
continuing,
{{{2x>32-2}}} ---> {{{2x>30}}}
{{{cross(2)x/cross(2)>cross(30)15/cross(2)}}}
{{{x>15}}},
Conclusion: Maria's age should be greater than 15 years for their sum will be greater than 32 years.
Check: if {{{x=15years}}} Maria's age
going back to the condition:
{{{15+15+2>32}}}
{{{32=32}}} --------> not greater than 32.
if {{{x=16years}}} Maria's age
{{{16+16+2>32}}}
{{{34>32}}} --------> CORRECT!
Maria's age should be 16 years or more to satisfy the condition.
Thank you,
