the sum of two numbers is 34. their difference is 18. what are the two numbers?
L-S=18
L+S=34
i still don't get bob help!!!!!!!!!!
EQUATION FIND N.
3,7,14,15,17,46,N
RANGE:43 MODE:N
MEDIAN:15 MEAN:N
L - S = 18
L + S = 34
L = 18 + S
(18 + S) + S = 34
18 + 2S = 34
2S = 34 - 18
2S = 18
S = ?
L = ?
First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.
See my answer to your later post.
Thanks for asking.
Why do math numbers have their shapes
To find the two numbers, we can set up a system of equations using the given information. Let's assume the first number is 'x' and the second number is 'y'.
From the problem, we have two pieces of information:
1) The sum of the two numbers is 34, which can be expressed as: x + y = 34.
2) The difference between the two numbers is 18, which can be expressed as: x - y = 18.
Now we have a system of equations:
Equation 1: x + y = 34
Equation 2: x - y = 18
To solve this system, we can use the method of substitution or elimination. Let's use the substitution method:
From Equation 2, we can isolate 'x':
x = y + 18.
Substitute this expression for 'x' into Equation 1:
(y + 18) + y = 34.
Simplify the equation:
2y + 18 = 34.
Subtract 18 from both sides of the equation:
2y = 34 - 18,
2y = 16.
Divide both sides of the equation by 2:
y = 8.
Now, substitute the value of 'y' back into Equation 2 to find 'x':
x - 8 = 18,
x = 18 + 8,
x = 26.
Therefore, the two numbers are 26 and 8.
