Math Problem Statement

Question 62: Is the equation 3(x - 2) = 3x - 6 true or false? Question 63: Is the equation -(x - 3) = -x - 3 true or false? Question 64: Is the equation 3(2x + 2y) = 6x + 6y true or false?

Solution

Let's go over the questions from the image step by step:

Question 62

The equation provided is: 3(x2)=3x63(x - 2) = 3x - 6 You are asked if this is true or false.

  • Start by expanding the left-hand side: 3(x2)=3x63(x - 2) = 3x - 6 This simplifies to: 3x6=3x63x - 6 = 3x - 6 Both sides are equal, so this equation is true.

Question 63

The equation provided is: (x3)=x3-(x - 3) = -x - 3 You are asked if this is true or false.

  • Start by expanding the left-hand side: (x3)=x+3-(x - 3) = -x + 3 Now compare with the right-hand side: x3-x - 3 These are not the same, so the equation is false.

Question 64

The equation provided is: 3(2x+2y)=6x+6y3(2x + 2y) = 6x + 6y You are asked if this is true or false.

  • Expand the left-hand side: 3(2x+2y)=6x+6y3(2x + 2y) = 6x + 6y Both sides are identical, so this equation is true.
