Please answer these questions with methods please.

Answer 1

Only the first question
10×(6+(-2))=10×6+10×(-2)
10×4=60+(-20)
40=40
hence Lhs=Rhs

Answer 2

1) 10 *(6-2) = 10*6 + 10*-2
60 - (-20) = 60 + -20
60 +20 = 60-20
80 = 40
LHS = RHS DOES NOT SATISFIES
...........................................................................................................................
2) (-15)* {(-7)+(-1)} = (-15) * (-7)+(-15) * (-1)
-15 *-7 +(-15) *(-1) = 105 +15
105 + 15 =120       = 120
= LHS = RHS
..........................................................................................................................
3) 10 *(6-(-2) = 10*6-10*(-2)
     10 *6+2    = 60-(-20)
      60+20  = 60+20
        80 = 80
lhs = rhs
..........................................................................................................................
4) (-15)*{(-7)-(-1)} =(-15)*(-7) -(-15)*(-1)
-15*-7 +(-15*-1) = -15 *-7+15*-1
105 -(-1) = -105 +(-15)
105+1 = 105-15
106 = 90
LHS =RHS  does not satisfy
..........................................................................................................................
(-49)*18 ; (-25)*(-31) ; 70*(-19)+(-1)*70
-882 ; 775 ;1330+(-70)
-882 + 755 +1330-70
-107 +1260
= 1153
