Answer:

-8

Explanation:

subtract 2x to move it to the left side

-2x-15=1

add 15 to move it to the right side then add 1 to 15 since it would be 15 plus 1

-2x=16

divide by -2 to get x by its self

-2x=16/2x

Answer:

see below

Explanation:

-15 = 2x + 1

Subtract 1 from each side

-15-1 = 2x + 1-1

-16 = 2x

Divide each side by 2

-16/2 = 2x/2

-8 =x

Check

-15 = 2(-8) + 1

-15 = -16+1

-15 = -15
