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
