1) 2x-3 = x -3 + x
2) 2x - 6 = -6 + 2x
3)
4) 3x+0 = 3x
5)
Step-by-step explanation:
We need to match each expression on the left with an equivalent expression on the right
The expressions are equivalent if the have the same results.
1) 2x - 3
Looking at the options the best match is:
x -3 + x
When solve we get:
2x-3
So, 2x-3 = x -3 + x
2) 2x - 6
Looking at the options the best match is:
-6 + 2x
Because according to commutative property: a+b = b+a
So, 2x - 6 = -6 + 2x
3)
First simplifying the given expression:
Looking at the options, -6.9+4.9 = -2
So,
4) 3x + 0
Looking at the options the best match is:
3x
Because, adding 0 in 3x will result in 3x
So, 3x+0 = 3x
5)
First simplifying:
Now, solving the option:
So,
