Question

GENTE ME AJUDEM PFVRRRRRR Resolva, no universo dos números reais, as equações: a) 3.(x – 2) +2. (4x -3) – 5. (2 –x) = 6. (x +3) +2x b) 2x – 12= ½

Answer 1

Resposta:

a) 3.(x – 2) +2. (4x -3) – 5. (2 –x) = 6. (x +3) +2x

3x-6+8x-12-10+5x=6x+18+2x

3x+8x+5x-6x-2x=18+6+12+10

10x=46

x=46/10

x= 4,6

b) 2x – 12= ½

2x-12=0,5

2x=0,5-12

2x=-11,5

x=-11,5/2

x= -5,75
