Question

me ajudem resolva as equaçoes a } x/3 +x/2=7+x/3 B} x-2/3+2x=5x/2 C] x-5 /3 +3x-1/2=4 D x-1/5=x-2x-1/3 a resposta de cada tem q dar a]14/3 b] -4 C] 37/11 e d ] -4

Answer 1

A)
x/3+x/2=7/1+x/3
2x+3x/6=42+2x/6
2x+3x=42+2x
5x-2x=42
3x=42
x=42/3
x=14/3 (o /3 é porque pega os divisores lá de cima)

B)
x-2/3 + 2x/1 = 5x/2
2x-4x+12x/6 = 15x/6
2x-4+12x=15x
2x-12x-15x=-4
x=-4
