For this case we have as a simpler method the factorization. We must find two numbers that multiplied as a result +3 and added as a result +4.

These numbers are:

Solve this equation showing work − 9 ≥− 8(1 + 6v) − 1
Flauer [41]

Answer:

v≥0

Step-by-step explanation:

−9≥−8(1+6v)−1

Step 1: Simplify both sides of the inequality.

−9≥−48v−9

Step 2: Flip the equation.

−48v−9≤−9

Step 3: Add 9 to both sides.

−48v−9+9≤−9+9

−48v≤0

Step 4: Divide both sides by -48.

−48v

−48

≤
