i needed points to ak a question
Step-by-step explanation:
Answer:
1)x=4
2)
Step-by-step explanation:
12x-14=34
step1: +14 on both sides
step2: 12x=48
divide 12 from both sides
step3:x=4
Answer: (0, 6)
Step-by-step explanation:
Let's look at the second equation and try multiplying it by 4:
4 * (3x + ky) = 4 * 27
Which gives us:
12x + 4ky = 108
This looks almost exactly like the first equation except that instead of -20y, there is 4ky. We could try making them equal to each other and solving for k:
-20y = 4ky
-20 = 4k
k = -5
Then, the answer is k = -5.
Answer:
When you subtract a negative number from another negative number then the second negative number will become positive and the minus sign will become an addition sign.
In this case:
-13 - (-13) = 0
-13 + 13 = 0
I hope I've helped explain this a little bit better to you.
