Verona is solving the equation –3 + 4x = 9. in order to isolate the variable term using the subtraction property of equality, which number should she subtract from both sides of the equation?

a: –4
b: –3
c: 3
d: 4

B: -3 thats the correct answer

Option B is correct.

Step-by-step explanation:

We have been given the equation -3 +4x =9.

To isolate the variable term means to separate x so, as to find the its value

She should subtract -3 from both sides after that she will get:

-3-(-3) +4x=9-3

It will become:

-3 +3 +4x=6

On simplification

4x=6

And finally, x=6/4

Therefore, option B is correct.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
