Whats 2(4k+3)-13=2(18-k)-13 solve
Tju [1.3M]

Answer:

k=3

Step-by-step explanation:

2(4k+3)−13=2(18−k)−13  

2(4k+3)−13=2(18−k)−13

(2)(4k)+(2)(3)+−13=(2)(18)+(2)(−k)+−13

8k+6+−13=36+−2k+−13

(8k)+(6+−13)=(−2k)+(36+−13)

8k+−7=−2k+23

8k−7=−2k+23  

8k−7+2k=−2k+23+2k

10k−7=23

 10k−7+7=23+7

10k=30

10k/10=30/10

k=3
