Question

Va rog frumos sa îmi rezolvați aceasta expresie cu necunoscuta

Answer 1

7000-70:{11+[(a:8+13)×101-1076]:2:8}+1=7000
-70:{11+[(a:8+13)×101-1076]:2:8}+1=7000-7000
-70:{11+[(a/8+13)×101-1076]×1/2×1/8}+1=0
-70:[11+(101a/8+1313-1076)×1/2×1/8]+1=0
-70:[11+(101a/8+237)×1/2×1/8]+1=0
-70:[11+(101a+1896)/8×1/2×1/8]+1=0
-70:(11+101a+1896)/128+1=0
-70:(1408+101a+1896)/128+1=0
-70:(3304+101a)/128+1=0
-70×128/(3304+101a)+1=0
-8960/(3304+101a)+1=0
-8960/3304+101a= -1
-8960= -(3304+101a)
-8960=-3304-101a
101a= -3304+8960
101a=5656
a=5656/101=>a=56
