Answer:i cant see it that well its blurry
Step-by-step explanation:
Answer:
I think that there is indefinite.
Step-by-step explanation:
The reason why is because <em>x and y </em>could be any number
The two equations given are
3x + y = 17 and 4x - y = 18
Now we will first take one equation
3x + y = 17
Then
y = 17 - 3x
Now replacing the value of y in the second equation we get
4x - y = 18
4x - (17 - 3x) = 18
4x + 3x - 17 = 18
7x = 35
x = 35/7
= 5
Putting the value of x in the first equation we get
3x + y = 17
(3 * 5) + y = 17
15 + y = 17
y = 17 - 15
y = 2
So the value of x is 5 and y is 2
X (unknown number at first is 28) is the number 28.
28/7=4. 2(28) divided by 7= is also 56 divided by 7.
Which is 8. 8 is the final answer.
