Enter Equation or Inequality
  

Solve the following equation

190-3t=100

Solve for t

190 - 3t = 100

Group constants

Group our constants 190 and 100.
subtract 190 from both sides

-3t + 190 - 190 = 100 - 190

Cancel 190 on the left side:

-3t = -90

Divide each side of the equation by -3

-3t
-3
=
  
-90
-3

t = 30

Final Answer

t = 30





What is the Answer?
t = 30
