Answer 2

Answer:

hii mate....

Step-by-step explanation:

10 x - 7 = 21

Move constant to the right hand side and change it sign ...

10x = 21 + 7

10x = 28

Divide both sides of the equation by 10 ...

x = 28 / 10 ( solve this and you will get answer = 14/5 )

x = 14 /5

Hence the answer is 14 by 5 now you can write it in as a mixed fraction or in the decimal form.......

x = 2.8
