Sure! Let's make it simpler for a 6th grader to understand.
To solve the problem \( 5(2k - 3) \geq -3(4 - 3k) \):
- Distribute the numbers:
-
On the left side, we do \( 5 \times 2k \) and \( 5 \times -3 \):
- \( 5 \times 2k = 10k \)
- \( 5 \times -3 = -15 \)
- So, the left side becomes \( 10k - 15 \).
-
On the right side, we do \( -3 \times 4 \) and \( -3 \times -3k \):
- \( -3 \times 4 = -12 \)
- \( -3 \times -3k = +9k \) (because a negative times a negative is a positive)
- So, the right side becomes \( -12 + 9k \).
-
Now our inequality looks like this: \[ 10k - 15 \geq -12 + 9k \]
-
Combine the like terms:
- We want to get all the \( k \) terms on one side. So let's subtract \( 9k \) from both sides: \[ 10k - 9k - 15 \geq -12 \]
- This simplifies to: \[ k - 15 \geq -12 \]
-
Isolate \( k \):
- Now we add 15 to both sides to solve for \( k \): \[ k \geq -12 + 15 \]
- Which simplifies to: \[ k \geq 3 \]
So, our final answer is: \[ k \geq 3 \]
That means any number that is 3 or bigger is a solution!
