What value of x satisfies -2x-7=12

-19/2

Step-by-step explanation:

we have -2x-7=12

add 7 to both sides getting us

-2x=19

divide both sides by negative 2 getting us

x=-19/2

-2m+7=11

you moved the 7 to the other side which means the sign changes so instead of a +7 it would be a -7 underneath the 11

-2m=11
-7

Then you subtract 11-7 so it would be a positive 4. its a positive because the 11 is greater than the -7.

-2m=4

You would have to divide the -2 on both sides so the m could be alone.

-2m/-2=4/-2

So the two negatives cancel each other out and 4/-2 would be a -2 so a negative and a negative would equal a positive

m=-2
