-1/5b-2/5=-2 the answer i got was b = 0 Lowest common denominator = 5 -1/5b (5) - 2/5 (5) = -2 (5) -5/5b - 10/5 = -10/5 + 10/5 +10/5 -5/5b = 0 x 5/5 x5/5 b = 0

b=8

Step-by-step explanation:

Given the equation

Step 1: Take the Lowest common multiple of the left hand side.

The LCM of 5 and 5=5.

Step 2: Combine using the LCM

Step 3: Cross Multiply

-b-2= -2 X 5

-b-2 =-10

Step 4: Add 2 to both sides

-b-2+2 =-10+2

-b=-8

Step 5: To solve for b, Divide both sides by -1

b=8

NOTE: In your steps given

-2 X 5 = -10

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
