-5/6q – (q – 1) = 1/4 (-q + 80)
~take out parentheses~
-5/6q – q + 1 = 1/4 (-q + 80)
~distribute the 1/4~
-5/6q – q + 1 = 1/4*-q + 1/4(80)
-5/6q – q + 1 = -1/4q + 20
[-11/6]q + 1 = -1/4q + 20
[-11/6]q + 1 – 1 = -1/4q + 20 – 1
[-11/6]q = -1/4q + 19
[-11/6]q + 1/4q = -1/4q + 19 + 1/4q
~find common denominator which is 12~
[-11*2/12]q + [3*1/12]q = 19
-22/12q + 3/12q = 19
-19/12q = 19
~multiply by the reciprocal, same as dividing by -19/12~
[-19/12q]*[12/-19] = 19*[12/-19]
q = -12
