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

Answer:

$m=-\frac{1}{2}$

Step-by-step 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

$-8m-8=-4$

$-8m=-4+8=4$

$m=\frac{4}{-8}=-\frac{1}{2}$

Hence, $m=-\frac{1}{2}$
