Question 966046

Let  x  be the Tony's age in years.

Then Sandy's age is  x + 35,  according to the condition.

Next,  you have an equation 


(x + 35) + x = 43.


Simplify and solve it:

2x + 35 = 43,

2x = 43 - 35,

2x = 8,

x = 4.


<B>Answer</B>. Tony is &nbsp;4&nbsp; years old, &nbsp;Sandy is &nbsp;4 + 35 = 39 years old.
