Answer: k= -8 Explaining: Move variable to the left-hand side and change its sign. 2.25k – 6.5k – 20= 6.5k – 6.5k + 14 Since two opposites add up to zero, remove them from the expression. 2.25k – 6.5k – 20= 14 Collect like terms! -4.25k = 14 + 20 Add the numbers -4.25k = 35 Divide both sides of the equation by -4.25 So you will get the answer: k= -8 Log in to Reply

Answer:

k= -8

Explaining:

Move variable to the left-hand side and change its sign.

2.25k – 6.5k – 20= 6.5k – 6.5k + 14

Since two opposites add up to zero, remove them from the expression.

2.25k – 6.5k – 20= 14

Collect like terms!

-4.25k = 14 + 20

Add the numbers

-4.25k = 35

Divide both sides of the equation by -4.25

So you will get the answer: k= -8
