2.25k - 20 = 6.5k + 14 please help me solve this step by step asap!

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
