Question

1. Write three expressions that are equivalent to 3x

For problem 2-9, determine whether that's who expressions are equivalent
if they are equivalent state the property of the operations are reasoning that justifies why two expressions are equivalent.
If they are not equivalent choose a number for the variable then using that number evaluate each expression to justify your answer

2. 5x
5x . 7 divided by 7

3. (4x + 3) + 7y
4x + (3+7y)

4. 5x - 2 + 3x
5x - 3x + 2

5. (9+4)x
9x+4x

6.10x - 6x divided by 2
4x divided by 2

7. 4(7+5x)
20x + 28

8. 3 + 2 (x + 4)

9. 9 + 2(3x+1)-2
9 + 6x
돕다!/HELP!

Answer 1

5x = 5. 5x 7/7= 5x, or if you were just asking 7/7= 1., (/ - means divide by aka) 4x+3+7y= 4x+7y+3, 4x + (3+7y) = 4z+7y+3, 5x-2+3x= 8x-2, 5x-2+3x=2x, x-3x+2= -2x+2, (9+4)x=13x, 10x-6x/2= 19x/2, 4x/2= 2x, 4(7+5x)= 28+20x, 20x+28= 4(5x+7), 3+2(x+4)=2x+11, 9+2(x+4)=2x+17, 9+6x= 3(3+2x).
