T=tom D=todd
T=4D "tom is now 4 times as old as todd"
T%2B3=13%2B2%28D%2B3%29 "in three years tom's age will be 13 years more than 2 times as old as tom" Remember to add 3 years to both T and D
use substitution to solve for D
T%2B3=13%2B2%28D%2B3%29 T=4D
%284D%29%2B3=13%2B2%28D%2B3%29 Use order of opperations
%284D%29%2B3=13%2B%282D%2B6%29 add
%284D%29%2B3=19%2B2D subtract
%282D%29=16 divide
D=8
T=4D substitute
T=4%288%29 multiply
highlight+%28T=32%29
