document.write( "Question 548406: Write an equation that models how old in years each of you will be, when your ages add up to 150 years old. For example, if x = your age and the eldest person was a year older than you, you would write their age as x + 1. Then the equation would be: x + (x+1) = 150. The ages are 53, 9, 40. \n" ); document.write( "
