Question 809522
{{{x}}}= Romy's age (in years)
{{{2x}}}= twice Romy's age (in years)
{{{2x-3}}}= 3 years less than twice Romy's age
 
If that is Gina's age, and Gina is 27 years old,
{{{2x-3=27}}} is the equation.
 
Solving:
{{{2x-3=27}}}
{{{2x-3+3=27+3}}}
{{{2x=30}}}
{{{2x/2=30/2}}}
{{{highlight(x=15)}}}
Romy is {{{highlight(15)}}} years old.
