Answer:
Is there an image?
Step-by-step explanation:
1. no because 2x+10 is not equal to 2x+7
2. no. you cant add una like terms so 4x+4 doesn’t equal 8x
3. yes. the terms still retain their same value although they are not in the same order
4. yes. when u distribute the -3, you get -3x-6 which is of course equal to -3x-6
The decimal adds a zero every time the powers of ten increase for example if u do 1 x

=100 if u do 1x

=1,000
