Remember to do the same thing to both sides

use distributive prpoerty which is
a(b+c)=ab+ac so
pemdas
multiplication
8(x+1/4)=8x+8/4=8x+2
3(6x-9)=18x-27

now we have7x+8x+2=18x-27-8
add like terms
15x+2=18x-35
subtract 15x from both sides
2=3x-35
add 35 to both sides
37=3x
divide both sides by 3
37/3=x
12 and 1/3=x

6w-19 + k when<br> w=8 and k = 2
ddd [48]

Answer:

31.

Step-by-step explanation:

1. Write out the problem.

6w-19 + k; w=8 and k=2

2. Figure out the first part of the problem.

So, if w=8 and 6 and w are next to each other, we should multiply 6*8, which is 48. Next, it says to subtract 19. 48-19=29.

3. Find out what the last part of the problem is.

Since the first part of the problem is 29 and k=2, we should add 29+2=31, which is the final answer.

Hope this helped :)
