Question
Ok this is a physics problem but solving it obviously
requires algebra which I haven't taken in a long time and I
don't how to get the answer. If you could tell me the answer
but also how you got it, I would appreciate it.

There are 3 equations, I have to use all 3 equations in
order to solve for T1, T2 and a.

T1-3.92=4a
T2-T1-1.96=2a
9.8-T2=a


Answer
I hit the wrong place and may have accidentally sent an answer before this one.

Using the 3rd equation, put that in the 1st and 2nd for a.
Solve the 2nd equation for T1 by subtractin T2 from both sides and adding 1.96 to both sides.

Put this value of T1 into the 1st equation.  Solve this equation for T1.  Put this value for T1 in the 2nd equation and solve for T2.

Put the value of T2 in the 3rd equation to find a.
