Question

Verify :-
15 x [ 3 + (-7)) = (5x3) + (15 X(-2)]​

Answer 1

Step-by-step explanation:

0.6x +

4

5

= 0.28x + 1.16

Transposing 0.28x to LHS and 4/5 to RHS, we get

=> 0.6x - 0.28x = 1.16 -

4

5

=> 0.32x = 1.16 - 0.8

=> 0.32x = 0.36

Dividing both sides by 0.32, we get

=>

0.32x

0.32

=

0.36

0.32

=> x =

9

8

Verification:

Substituting x =

9

8

on both sides, we get

0.6(

9

8

) +

4

5

= 0.28(

9

8

) + 1.16

5.4

8

+

4

5

=

2.52

8

+ 1.160.675 + 0.8 = 0.315 + 1.161.475 = 1.475

LHS = RHS

Hence, verified
