Tofind:The two numbers such that their sum is -3 and 3 times of one is 27 greater than other.
Answer to Problem 6CR
The option B is correct.
Explanation of Solution
Given information:
The sum of two numbers is -3 and three times the first number minus the second number is 27.
Formulaused:
We obtain two liner equations from given conditions and solve them.
Calculations:
Let two numbers are x and y, then according to condition, first their sum is -3, therefore,
According to second condition, three times of the first number, i.e., 3x minus second number is 27, therefore,
Now, adding equation (1) and (2)
Further, substituting value of x in equation (1)
Thus, two number are 6 and -9.
Hence, the option B is correct.
Conclusion:
The option B is correct.
