The larger of two numbers is 7 more than 5 times the other. Their sum is 55. Find the two numbers.
Answers
Answer:
Step-by-step explanation:
8 and 47
Final answer:
The question involves finding unknowns from a system of linear equations. By assigning 'x' as the smaller number and 'y' as the larger number, we establish two equations based on the provided information. Solving these equations, we find the smaller number to be 8 and the larger number to be 47.
Explanation:
This question involves the system of linear equations in Mathematics. To find the two numbers, establish two equations based on the information given. Let's denote the smaller number as 'x' and the larger one as 'y'.
1. The larger of two numbers is 7 more than 5 times the other, which translates into the equation:
2. Their sum is 55, which gives us the second equation: x + y = 55.
Substitute the first equation into the second, we get: Simplifying it gives us
, further simplifying leads to 6x = 48, thus x = 8. Substituting x = 8 into
we get y = 47. So, the smaller number is 8 and the larger number is 47.

Answer:
x is less than negative 2
Step-by-step explanation:
Using the properties of addition, we move the 7 over to the five, making it negative.
This makes negative 2 because we subtract 7 from 5.
Then, we can flip the equation to understand it better, making the x in the front.
This makes the final solution x is less than -2
