document.write( "Question 560926: The sum of the digits of a two-digit number is 8. If the number is multiplied by 4, the result is 104. Write and solve a system of equations. Find the number.\r
\n" );
document.write( "\n" );
document.write( "I thought the system is x+y=8 and 4z=104
\n" );
document.write( "Although then I thought that the couldn't be solved by graphing becuase there is no z-axis, no substitution because the variables aren't the same to plug back into, and not elimination because there is not two like variables to be the same but opposite and eliminate. I know the number is 26 but I dont know the equations. \n" );
