For which value of x is the equation 3(3 + x) = 15 + x true?

x=3

Step-by-step explanation:

3(3 + x)=15+x

distribute

9 + 3x=  15+x

subtract x from each side

9+3x-x = 15

9+2x = 15

subtract 9 from each side

9+2x-9 = 15-9

2x = 6

divide by 2

2x/2 = 6/2

x=3

X = 3

Step-by-step explanation:

To solve for x, you can first divide both sides of the equation by 3. The reason you do this is because the left side is being multiplied by 3, so dividing would cancel it out

(3(3 + x) = 15 + x)/3   =  3 + x = 5 + 1/3x

Now, subtract 3 from both sides to isolate x on the left side

x = 2 + 1/3x

Lastly, subtract 1/3x from both sides

2/3x = 2

Now, divide both sides by 2/3 to get x = 3.
