Answer:
22 and 7
Step-by-step explanation:
Let x and y be the two numbers we are looking for:
The statement “their sum is 29” means x + y = 29
The statement “their difference is 15” means x - y = 15
we get this system:
x + y = 29 (1)
x - y = 15 (2)
Let’s solve it :
(1) + (2) ⇒ x + y + x - y = 29 + 15 ⇒ 2x = 44 ⇒ x = 44/2 = 22
Now we replace x by 22 in equation (1) :
22 + y = 29 ⇒ y = 29 - 22 = 7
The answer is 18.
Just replace the x with 2

Answer:
We taking the same final exam
Step-by-step explanation:
I don’t know the answer that’s why I came here
Simplifying
-4v + 2v = -12
Combine like terms: -4v + 2v = -2v
-2v = -12
Solving
-2v = -12
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Divide each side by '-2'.
v = 6
Simplifying
v = 6
