Answer:

x=9

Step-by-step explanation:

Isolate the variable you are solving for.

In this case, -5x needs to be divided by -5 to isolate x. But you must do to one side of the equation what you did to the other, so -45 must also be divided by -5x.

-5x/-5=-45/-5

x=9

-5x=-45 divide -5 on both sides...
The -5’s cancel out and you’re left with
-45 divided by -5 a (-) divided by another (-) is a (+). So the answer is x=+9 or just x=9 that’s also fine. Hope that helps

11b-7-3n+8-5b+9n what is the answer

Sergio [31]

Answer:

6 n + 6 b + 1

Step-by-step explanation:

Simplify the following:

11 b - 7 - 3 n + 8 - 5 b + 9 n

Grouping like terms, 11 b - 7 - 3 n + 8 - 5 b + 9 n = (9 n - 3 n) + (11 b - 5 b) + (8 - 7):

(9 n - 3 n) + (11 b - 5 b) + (8 - 7)

9 n - 3 n = 6 n:

6 n + (11 b - 5 b) + (8 - 7)

11 b - 5 b = 6 b:

6 n + 6 b + (8 - 7)

8 - 7 = 1:

Answer: 6 n + 6 b + 1
