Answer:
x =3 and y =1
Step-by-step explanation:
( x+y , x-2y) = (4 , 1)
compare their corresponding elements
x+y = 4
y = 4 - x equation (i)
x-2y =1
substitute the value of x
x - 2(4 - x) =1
x - 8 + 2x =1
3x = 1 +8
x = 9/3
x = 3
Now substitute the value of x in equation (i)
y = 4 - x
y = 4 - 3
y = 1
Answer:
u=-1
Step-by-step explanation:
if you replace with a or b the answer on the left side is actually bigger since it is closer to 0 than -20. same with choice d
choice c makes -12-28 which is a smaller value than -20
is the equation in the question written like the one in the bottom? Because for me to help you I must confirm what the equation looks like.

Answer: 1
Step-by-step explanation:
Answer:
1st Option;
j = 4.5
k = 2
Step-by-step explanation:
Let's solve for "j" first:
=> We know that by the definition of midpoint segment theorem we can say;
3j = 5j - 9
0 = 5j - 3j - 9
0 = 2j - 9
0 + 9 = 2j
9 = 2j
9/2 = j
4.5 = j
=> Now that we have j-value we use the same method to solve for k-value;
6k = k + 10
6k - k = 10
5k = 10
k = 10/5
k = 2
Therefore;
j = 4.5
k = 2
<u>So the first option would be correct!</u>
Hope this helps!
