Question

x + 3/2 - x/5 - 2/5 = 1

Answer 1

x + 3/2 - x/5 - 2/5 = 1 
x/1 + 3/2 - x/5 - 2/5 = 1/1

10x + 15 - 2x -4 =10
-----------------------------
               10
10x -2x = 10 +4 -15
8x = 14 -15
8x = -1
x = -1/8
S={ -1/8 }

Answer 2

Tirando o m.m.c de 2, 5, 5 = 10 10X 15 - 2x - 4 = 10 Corta o 10 do denominador 10X - 2X + 15 - 4 = 10 8X + 11 = 10 8X = 10 - 11 8X = - 1 X = - 1/8
