Answer: k=3/5

Explanation:

distributive property: a(b+c)=ab+ac

divide by 7 both sides of an equation.

7(5k-4)/7=-7/7

simplify by equation.

5k-4=-1

add 4 both sides of an equation.

5k-4+4=-1+4

simplify.

5k=3

divide 5 both sides of an equation.

5k/5=3/5

simplify.

k=3/5

Hope this helps!

Thanks!

Have a great day!
