Don's nephew is 5 years less than triple Don's age. The sum of Don's age and his nephew's age is 50. Write an equation to represent this relationship.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
