  yes

Step-by-step explanation:

3x and -3x are like terms. When they are added, the result is zero.

  3x -3x = 0

This fact is used extensively in the solution of equations.

Example

  2x +3 = 3x

To solve this, we can add the term -2x to both sides of the equation. Then collecting terms gives 0 for the sum of x-terms on the left side. (That is why we chose -2x.)

  2x -2x +3 = 3x -2x . . . . . add -2x to both sides

  3 = x . . . . . . . collect terms

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
