Question 627985: Good afternoon ^.^ i was wondering if someone could show me how to solve this problem : "when 75 is subtracted from four times Tamu's age, the result is Tamu's age. How old is Tamu?" i'd appreciate it :) please and thank you! Answer by jim_thompson5910(35256) (Show Source):
"when 75 is subtracted from four times Tamu's age, the result is Tamu's age"
translates to
4T - 75 = T
Let's solve for T
4T - 75 = T
4T - 75 - 4T = T - 4T ... Subtract 4T from both sides.
-75 = -3T ... Combine like terms.
-3T = -75 ... Flip the equation
-3T/(-3) = -75/(-3) ... Divide both sides by -3.
T = 25 ... Divide
So Tamu is 25 years old
