Write an equation for each statement\r
\n" ); document.write( "\n" ); document.write( "alex is x years old.
\n" ); document.write( "a = x
\n" ); document.write( " June is 7 years older than alex.
\n" ); document.write( "j = x+7
\n" ); document.write( " In 5 years, their total combined age will be 31 years
\n" ); document.write( "(x+5) + (j+5) = 31
\n" ); document.write( "Write a linear equation for their total combined age in 5 years
\n" ); document.write( "Replace j with (x+7)
\n" ); document.write( "x + 5 + (x+7) + 5 = 31
\n" ); document.write( "2x + 17 = 31
\n" ); document.write( "we can solve it
\n" ); document.write( "2x = 31 - 17
\n" ); document.write( "2x = 14
\n" ); document.write( "x = 7 is A's age
\n" ); document.write( "then
\n" ); document.write( "14 = J's age
\n" ); document.write( "
\n" );
