In order to find the correct answer you much make an equation that =110

anonymous · Answer

I don't know how to write the equations.

anonymous · Answer

Well let's work it out then. We can start by writing the =110

anonymous · Answer

One step and two step equations = 1070

anonymous · Answer

One step is O 
Two step is T

0-2T=110

anonymous · Answer

But 0-2T = 1070, so we must find that first. Let's see what happens when we divide 1070 by 3. What do you get?
