Question

calculo cada um dessa conta ; a) f(x)= 6 ==> 6 = 4x - 2/3 ==> 4x = 6+2/3 ==> 12x = 18+2 ==> 12x=20 ==> x = 20/12

b)f(x)= -10 => -10 = 4x - 2/3 => 4x = -10+2/3 => 12x = -30+2 => 12x=-28 => x = -28/12

c)f(x)= 0 ==> 0 = 4x - 2/3 ==> 4x = 0+2/3 ==> 12x = 2 ==> 12x=2 ==> x = 2/12

d)f(x)= 1 ==> 1 = 4x - 2/3 ==> 4x = 1+2/3 ==> 12x = 3+2 ==> 12x=5 ==> x = 5/12
