Question

Qual é o valor de x-y? sendo que:
x=2 (+3/2) + (-2/3)

y= (+1/4) - 2. (3/2)

Me ajudem!!!!!

Answer 1

x - y = ?
x = 2 (+3/2) + (-2/3)
y = (+1/4) - 2 .(3/2)

x = 6/2  - 2/3
x = 3 /1 - 2/3
x = 9/3 - 2/3
x = 7/3

y = 1/4 - 6/2
y = 1/4 - 3/1
y = 1/4 -  12/4
y = -11/4

x - y = 7/3 - (-11/4) = 7/3  +  11/4  = 21/12  +  33/12 = 54/12=9/2
