Answer:
<h3>29 and 32</h3>
Step-by-step explanation:
Let x = number
Let y = second number
We know that there are two true equations from this. Here is shown below the equations.
x + y = 61
x + 3 = y
We could use the substitution method for finding the numbers. After that, we continue on to solve to find the first number.
x + (x+3) = 61
2x + 3 = 61
2x = 58
2x/2 = 58/2
x = 29
Now that we know that the first number is 29, plug it in to the second equation to find the second number.
x + 3 = y
29 + 3 = y
y = 32
Proof that these numbers are the correct answer:
32 + 29 = 61
61 = 61 (Which is true!)
To support me, please give me the brainliest answer. It would be greatly appreciated. Thank you!

Second one 30
here is my answer. i beleive i answered all of them. but i answered all i know hope it helps!
Answer:
Step-by-step explanation:
Answer: x = 7 and y = -2
Step-by-step explanation:
2x +3y = 8 ----------------(1)
x-y = 9 ----------------------(2)
multiply (2) by 2
2x-2y = 18--------------------(3)
subtract (2) from (3)
-5y = 10
Divide bothside by -5
y = -2
Similarly, multiply (2) by 3
3x-3y = 27-----------------------(4)
add (1) and (4) together
5x = 35
Divide bothside by 5
x= 7
Therefore, x =7 and y= -2
