Question

X=1/5,y=3/7 that -(x+y)=-(x)+(-y)

Answer 1

Answer:

∴ -22/35 = -22/35

Step-by-step explanation:

solution,

   -(x+y)=-(x)+(-y)

or, - (1/5 + 3/7) = -(1/5) + (-3/7)

or, - (1×7/5×7 + 3×5/7×5) =  -1/5 - 3/7

or, - (7/35 + 15/35) = (-1×7/5×7) - ( 3×5/7×5)

or, -(7+15/35) = -7/35 - 15/35

or, -(22/35) = (-7-15)/35

∴ -22/35 = -22/35
