Question

a) 10 -8 [x - 5(x - y)] b) - 2 [X-6 ( 2w - Z)] + 6x c) -5 + 3[x - 5( 3w-y+ 4z )] + 10



Por Favor ​

Answer 1

Explicación paso a paso:

a) 10 -8 [x - 5(x - y)] =

10 -8 [x - 5x + 5y]=

10 - 8[-4x + 5y]= 10 + 32x - 40y

b) - 2 [X-6 ( 2w - Z)] + 6x=

-2 [ x -12w +6z] + 6x=

-2x + 24w -12z + 6x= 4x + 24w - 12z

c) -5 + 3[x - 5( 3w-y+ 4z )] + 10=

-5 + 3[x - 15w + 5y - 20z] + 10=

-5+3x -45w+15y-60z+10= 5+3x-45w+15y-60z
