Issac is 78 years younger than Tatiana. 8 years ago Tatiana was 4 times Issac's age. how old is Issac now
\n" ); document.write( "

Let Isaac's (I'll use Isaac) age be I
\n" );
document.write( "Then Tatiana's is: I + 78
\n" );
document.write( "We then get the following AGE equation for Isaac: I + 78 - 8 = 4(I - 8)
\n" );
document.write( "I + 70 = 4I - 32
\n" );
document.write( "I - 4I = - 32 - 70
\n" );
document.write( "- 3I = - 102
\n" );
document.write( "I, or Isaac is:  \n" );
document.write( "

\n" );
