You can put this solution on YOUR website!
kristine, jake, and lexi are cousins.
\n" ); document.write( "Write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( "jake is 2 years older than kristine
\n" ); document.write( "j = k + 2
\n" ); document.write( "we want to get k in terms of j, like the next equation,
\n" ); document.write( "subtract 2 from both sides and we can write it
\n" ); document.write( "k = j - 2
\n" ); document.write( ":
\n" ); document.write( "lexi is 8 years younger than jake.
\n" ); document.write( "l = j - 8
\n" ); document.write( ":
\n" ); document.write( "the sum of their ages is 35.
\n" ); document.write( "k + j + l = 35
\n" ); document.write( "Replace k with (j-2) and l with (j-8)
\n" ); document.write( "(j-2) + j + (j-8) = 35
\n" ); document.write( "combine like terms
\n" ); document.write( "3j - 10 = 35
\n" ); document.write( "3j = 35 + 10
\n" ); document.write( "3j = 45
\n" ); document.write( "j = \"45%2F3\"
\n" ); document.write( "j = 15 yr is Jake's age
\n" ); document.write( ":
\n" ); document.write( "Find L's age
\n" ); document.write( "l = 15 - 8
\n" ); document.write( "l = 7 yrs is Lexi's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "You should check this by finding k's age and see that the sum of all three ages add up 35\r
