Question

please solve these sums and snd the pic...​

Answer 1

Answer:

13=2(x-5)-2

13=2x-10-2

- - = + but the sign is minus

Now,

13= 2x-12

13=10x

13-10=x

3=x

x=3

Answer 2

Answer:

1)

Step-by-step explanation:

1) given equation , 13= 2(x -5 ) -2

so , 13 = 2x - 10 - 2

13 = 2x -12

13 +12 = 2x

25 = 2x

or , x = 25/ 2

2) given equation , 17 X (5+(-2)) =( 17X 5 )+ ( 17X -2)

solving left hand side,

we get , 17 X 3

= 51

now solving right hand side ,

= 95 - 34

=51

here , LHS = RHS

hence verified

3) given equation ,

(-18) / (-6) / [-17 +16]

= 3/ (-1)

= -3
