I'll do the first three to get you going in the right direction

# 1


%28z%2B3%29%2F2%2B+7%2F2=%28%28z%2B3%29%2B7%29%2F2=%28z%2B3%2B7%29%2F2=%28z%2B10%29%2F2




# 2


3%2Fz+-+%28z-4%29%2Fz=%283-%28z-4%29%29%2Fz=%283-z%2B4%29%2Fz=%28-z%2B7%29%2Fz





# 3





Note: You are only allowed to add and subtract fractions only if EVERY denominator is equal to one another
