So I am having some trouble solving these equations!

    1. The problem statement, all variables and given/known data

    Elementary I know but could I please get some help solving the following four equations. It's simple calculus but I'm getting nowhere with what I have done!!


    Solve for T1, T2, a1, a2


    2. Relevant equations

    m2g-T2 = m2 (a1-a2)
    m3g-T2 = m3 (a1+a2)
    T1-T2 = 0
    T1-μm1g = m1a1


    (note that the the numbers after a and t are not numerical values. Just to show that the T1 has a different value for T2 etc. )

    3. The attempt at a solution

    So I have tried combining equations
    m2g-T2 = m2 (a1-a2)
    m3g-T2 = m3 (a1+a2)

    and ended up with g = a1- a2(m2+m3)/(m2-m3)


    After that I just can't figure out what to do next!
    any suggestions?
