Question

a-(3a-2a-5/10)-2a-57/6=-5/3

Answer 1

The answer is a 283/-22

Answer 2

a-(3a - (2a - 5)/10-(2a - 57)/6 = -5/3
a-(30a-2a+5)/10-(2a-57)/6 = - 5/3
after - +
a-(28a+5)/10-(2a-57)/6 = - 5/3
lcm
a-(84a+15-10a+285)/30 = - 5/3
after - +
a-(74a+300)/30 = -5/3
a-(74a+300)/30+5/3 = 0
lcm
a-(74a+300+50)/30 = 0
a-(74a+350)30 = 0
(30a-74a-350)/30 =0
(-44a-350) = 30
-44a = 350+30
-44a = 380
-11a = 95
-a = 95/11
