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.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
