Answer:
B, C
Step-by-step explanation:
7 - x = 18
A.
7 - 2x = 18 - x
126 - 14x = 324 - 18x
We are nowhere near the solution.
B.
-x = 11
x = -11
This works.
C.
7 = x + 18
-11 = x
This works.
D.
25 - x = 36
-25 + x = -36
This does not help.
E.
7 = x + 18
0 = x + 11
We still do not have a solution.
Answer: B, C
Answer:
<u> y = 19/36</u>
Step-by-step explanation:
Assuming that what you want is the value of y, you can pass all the right side stuff to the left, and the y to the right:
2/3 + 15/6 = 6y
Then you can sum the fractions on the left by using the same denominators:
4/6 + 15/6 = 6y ==> 19/6 = 6 * y
then you can pass the 6 that is multiplying on the right to the left - now dividing:
<u> y = 19/36</u>
