The numbers are
and ![18\frac{2}{3}](/tpl/images/0878/6970/675cb.png)
Step-by-step explanation:
Let x and y be the numbers
According to the statement, "The sum of two number is 18.", first equation will be:
And according to "The sum of two number is 18. 5 times the first number subtracted from 4/7bof the second number is 14." Second equation will be:
Multiplying whole equation by 7
From equation 1
Putting this in second equation
Putting x = -2/3 in equation 1
Hence, the numbers are
