(x^2/y)^4×(y^2/x)^-2​

Jawaban:

10

Penjelasan dengan langkah-langkah:

x/2 + y/4 = 6 –> 2x + y = 24…(1)

y/6 – z/2 = -2 –> y -3z = -12…(2)

z/4 + x/3 = 4 –> 4x+3z = 48..(3)

.

y – 3z =-12

4x + 3z = 48

.(+) ->

4x+y =36

2x+y = 24

..(-) –>

2x = 12

x = 6 , y = 24-2x = 12

y -3z = -12 –> 12 – 3x = 12

-3z = 24 –> x = -8

.

x+y+z = 6 + 12 -8 = 10
