You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.
Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.
2(4) + 4k - 9 = (4)(4) - (4) + 1
Then 8 + 4k - 9 = 16 - 4 + 1, or 4k - 1 = 13. Then 4k = 14, and k = 14/4, or (after reduction) k = 7/2
If the parameter k equals 7/2, then x = 4 is a solution to the given equation.
To check this out further, start with the proposed solution x = 5 and find k.
Multiply straight across:
-6 x -8 = 48
5 x 9 = 45
Simplify:
48/45 = 16/15
16/15, or 1 1/15 is your answer
hope this helps
Answer:
Step-by-step explanation:
10
Answer:
19
Step-by-step explanation:
9 - (-10) = ?
To do this, we need to use the additive inverse and the method of K(eep)F(lip)C(hange)
So, the problem becomes: 9 + 10 = ?
Do the math, and you get your answer of 19.
