Question

Which of the following is a solution of the equation 9 - 2x = -1?

(A) -5
(B) 5
(C) 4
(D) -4

Answer 1

x=5 which is choice B .

Answer 2

Answer: B) X = 5

Explanation:

You need to get x by itself to find the solution, that means adding/subtracting anything around it first which is 9.

your new equation would be -2x = -10

to get x completely alone, divide it by -2 and divide the other side, it makes x = 1 which is how to solve for it, when you divide -10 by it you get the answer of x = (B) 5
