# Fast which equation is not an identity? a) 0+7=7b) 1∙9=9c) x+3=3+xd) x+1=x21. which equation has no solution? a. 7y + 9 = −7y − 9b. 5x + 2 = 5x − 3c. 4v − 3 = 4v + 6 − vd. 2z + 1 = 3z − z + 122. solve the following equation3x + 4 = 5x − 1023. solve the following equation2(2x + 1) = 4x − 524. solve the following equation−2x − 2 = 2(3x − 1) − 4(−6 + 5x) kaylienguyen

D

Step-by-step explanation:

If you add 0 to anything, you do not have anything new when you are finished. A is an identity.

When you multiply 1 times anything, you do not get anything new. B is an identity

When you switch the order of two numbers and they are not affected by signs, then you are using the commutative property of addition. Nothing changes. C is an identity.

D is the problem child. Nothing I can think of right now will not change will you add 1 to it. If you can think of something that doesn't change when you add one to it, please put it in the comments. Otherwise, D is not an identity. awkwardkid0123

The first answer to your first question is option D, write down your equations in a notebook and start writing stuff down so you can learn well. Your doing great
