If $45 is the total charge to make a negative and 20 prints from an old photograph, what is the value of x?\r

You can put this solution on YOUR website!
equation is x+(3x/5)(10)+(x/5)(10)=45\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x+(3x/5)(10)+(x/5)(10)=45\r
\n" ); document.write( "\n" ); document.write( "x+6x+2x=45\r
\n" ); document.write( "\n" ); document.write( "9x=45\r
\n" ); document.write( "\n" ); document.write( "x=5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: x=5
