Answer:
We need to find the value of b to make 8b - 27 be equal to 5, so:
8b - 27 = 5
We solve the equation:
8b = 5 + 27
8b = 32
We divide both sides by 8:
b = 32/8 = 4
So now, we know that b=4, and we can verify:
8*4 - 27 = 5
32 - 27 = 5 TRUE
Answer:

Step-by-step explanation:
3x=6x-2
Subtract '3x' from both sides
0=3x-2
Add '2' to both sides
2=3x
Divide by 3
x=2/3
If you need the answer in decimal form divide 2 by 3
