Question 135 I feel ashamed that i dont know maf or how to spel

k = 3

Step-by-step explanation:

=> 4.5 + 1.5 k = 18 - 3k

=> 1.5 k + 3k = 18 - 4.5

=> 4.5 k = 13.5

Dividing both sides by 4.5

=> k = 3

k = 3

Step-by-step explanation:

4.5 + 1.5k = 18 - 3k

Add 3k to both sides.

4.5 + 4.5k = 18

Subtract 4.5 from both sides.

4.5k = 13.5

Divide both sides by 4.5

k = 3

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
