k = 5/3
Step-by-step explanation:
1. Distribute the 3 to 2x and - 3
(-3k + 4) + (6k - 9) = 0
2. Since we're adding (you can always do this when subtracting/adding parantheses), you can remove the parentheses. They do nothing extra to the equation.
-3k + 4 + 6k - 9 = 0
3. Add like terms (k's and whole numbers)
3k - 5 = 0
4. To solve for K, we need to add 5 to both sides of the equation.
3k = 5
5. Divide both sides by 3.
k = 5/3
Use this step by step solution to find whatever you're looking for.

Step-by-step explanation:
(-3k + 4) + 3 (2k - 3) = - 3k + 4 + 3*2k - 3*3
= - 3k + 4 + 6k - 9
= 3k - 5
When two numbers are in different sign, subtract and the result will carry sign of the bigger number.
