Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m?

1) -15m = -4m

2) -7m - 8 = m - 4

3) -3m - 8 = 4 - m

4) m - 4 = -7m - 8

5)-8 - 7m = -4 + m

6)-8 - 3m = 4 - m

Answer 1

Answer:

2 and 5 for sure. I think 4 is correct, but your teacher may not.

Step-by-step explanation:

The given expression reduces down to -7m - 8 = m - 4

1 cannot give -15m on the right. One seldom sees that mistake on Brainly.

3 does not do that. - 3m is not - 7m

4 has it's sides reversed. I would count it is right, others may not. I'm trying to say the left side is on the right side and the right side is on the left. That to me is OK.

5 is Ok as well the left is written as -8 - 7m which is -7m - 8. and with -4 and m

6 has been reduced on the left incorrectly. the right is it's signs backwards

2 4(?) and 5
