Answer 2

\[-2s-6s=13+19\]\[-8s=32\]

Answer 3

Simplifying
-2s + -19 = 6s + 13

Reorder the terms:
-19 + -2s = 6s + 13

Reorder the terms:
-19 + -2s = 13 + 6s

Solving
-19 + -2s = 13 + 6s

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-6s' to each side of the equation.
-19 + -2s + -6s = 13 + 6s + -6s

Combine like terms: -2s + -6s = -8s
-19 + -8s = 13 + 6s + -6s

Combine like terms: 6s + -6s = 0
-19 + -8s = 13 + 0
-19 + -8s = 13

Add '19' to each side of the equation.
-19 + 19 + -8s = 13 + 19

Combine like terms: -19 + 19 = 0
0 + -8s = 13 + 19
-8s = 13 + 19

Combine like terms: 13 + 19 = 32
-8s = 32

Divide each side by '-8'.
s = -4

Simplifying
s = -4

Answer 4

Now what do you do to verify it's right?

Answer 5

Put the answer back into the equation.

Answer 6

@MollyNicole2015 is correct :)

Answer 7

Right! Do it.

Answer 8

:) Thanks

Answer 9

-2 x -4 – 19 = 6 x -4 + 13
-2 x -4 - 19 = -11
6 x -4 + 13 = -11
-11 = -11
