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


-15m = -4m

-7m - 8 = m - 4

-3m - 8 = 4 - m

m - 4 = -7m - 8

-8 - 7m = -4 + m

-8 - 3m = 4 - m

Answer 1

first you have to find out the formula meaning you have to find out what m is then plug it in

Answer 2

Actually you don't at all. First you combine like terms on both sides so
-2m - 5m - 8 will turn into -7m - 8
and 3 + (-7) +m will turn into -4 + m
So the answer is...?

Answer 3

2nd one and 3rd one and 4th

Answer 4

It can't be the second one because m is negative, it can't be the third one because there is a -3m and that isn't part of the combined like terms, it can't be the 4th one because m - negative and the sides are switched. It's actually the 5th one.

Answer 5

Solve for y.

7y - 6y - 10 = 13



y = -23

y = -3

y = 3

y = 23
