Question

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

Answer 1

I hope this helps you



-7m-8=-4+m


-7m-m=-4+8

-8m=4

m=-1/2

Answer 2

`m=-(1)/(2)`

Explanation:

We are given that an equation

`-2m-5m-8=3+(-7)+m`

We have to find an equation which is equivalent to given equation

Combine like terms

`-7m-8=-4+m`

Subtraction property of equality

`-7m-m-8=-4`

Combine like terms

`-8m-8=-4`

`-8m=-4+8=4`

`m=(4)/(-8)=-(1)/(2)`

Hence,
`m=-(1)/(2)`
