is the number in brackets the correct solution to the equation show me how to solve this question a)5x=20 (-4)

Answer 1

5 multiplied by a number = 20
The number must be 4.
Let the number be x:-
5 x = 20
x = 4.

Examples
10 y = 50
y = 5

4 p = 12
p = 3

Hope this helps.

Answer 3

4

Answer 4

No.

5x = 20 is the same as 5 x _ = 20

5 x what equals 20?

The way to solve this is to get x on one side of the "="

5x / 5 = x and 20 / 5 = 4 so x=4.

Answer 5

The number in the brackets is not the correct solution to the equation.
5x=20 => x = 20/5 => x=4.

With due respect, I feel the question is pretty silly.

Answer 6

No.

This is how you would solve 5x = 20. First you need to isolate the variable, which is x.
5x = 20
5x / 5 = 20/5
x = 4

As you can clearly see, the answer wouldn't be -4. It would be positive 4.

Answer 7

No, it is not correct.

5x = 20
move 5 to the other side of equal sign
x = 20/5
x = 4

if x had equaled -4, then the answer would not be 20, it would be -20.

Answer 8

no...x=4

Your goal is to isolate x. That is, get x by itself on one side of the equation. You can do anything you want to the equation as long as you do it on both sides of the equal sign. In this case, if you divide 5x by 5, you will get x by itself. Then you must do the same on the other side, and divide 20 by 5. This gives you x=20/5, or x=4.

Answer 9

5 * x = 20

x = 20 / 5

x = 4

Answer 10

no.
5(-4) = -20
positive times a negative = a negative
positive times a positive = a positive
negative times a negative = a positive

so 5(4) = 20
or if it were -5(-4)
then the answer would be 20 as well
