Answer:

k = -1

Explanation:

13 = -4k + 9

Flip the equation

−4k + 9 = 13

Subtract 9 from both sides

−4k + 9 − 9 = 13 − 9

−4k = 4

Divide both sides by -4

−4k / -4 = 4 / -4

Simplify

k = -1

Answer:

k=-1

Step-by-step explanation:

13=-4k+9

switch sides

-4k+9=13

subtract 9 from both sides

-4k+9-9=13-9

simplify

-4k=4

divide both sides by negative 4

-4k/-4=4/-4

simplify

k=-1
