2e+t=3 solve for toast
t=3-2e then we are told
e+t=1.8 now use t found above and you get
e+3-2e=1.8 combine like terms on left
-e+3=1.8 subtract 3 from both sides
-e=-1.2 divide both sides by -1
e=1.20 and since e+t=1.8 then
t=0.6
So an egg costs $1.20 and a piece of toast costs $0.60
t=3-2e then we are told
e+t=1.8 now use t found above and you get
e+3-2e=1.8 combine like terms on left
-e+3=1.8 subtract 3 from both sides
-e=-1.2 divide both sides by -1
e=1.20 and since e+t=1.8 then
t=0.6
So an egg costs $1.20 and a piece of toast costs $0.60
