Show work

Answer 1

s=8

Explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer 2

9 − 2s − 10s = –10s − 7

Cancel equal terms on both sides of the equation

9 - 2s = - 7

Move the constant to the right-hand side and change its sign

-2s = - 7 - 9

Calculate the difference

-2s = -16

Divide both sides of the equation by -2

s = 8
