Answer:
![x=3](https://tex.z-dn.net/?f=x%3D3)
Step-by-step explanation:
The first step is to isolate the variable on one side. In this case, let's try to bring x to the right. We do this by adding 3x to both sides, which gives us:
![7 = 2x + 1](https://tex.z-dn.net/?f=7%20%3D%202x%20%2B%201)
Now, to have just the x term on the right, we subtract one from both sides of the equation, giving:
![6 = 2x](https://tex.z-dn.net/?f=6%20%3D%202x)
The last step is to divide both sides by two to leave x by itself. Thus, after dividing, we get:
![3 = x](https://tex.z-dn.net/?f=3%20%3D%20x)
Hope this helps!
Answer: 213
Step-by-step explanation:
Given :
![3 , 9 , 15 , ...](https://tex.z-dn.net/?f=3%20%2C%209%20%2C%2015%20%2C%20...)
The difference between the first term and the second term is 6 and the difference between the third term and the second term is 6 , this means that the sequence is an Arithmetic sequence.
The formula for calculating the nth term of an arithmetic sequence is given as :
= ![a + (n-1)d](https://tex.z-dn.net/?f=a%20%2B%20%28n-1%29d)
where :
a = first term
n = number of terms
d = common difference
Therefore , the 36th term will be :
= ![3 + (36-1)(6)](https://tex.z-dn.net/?f=3%20%2B%20%2836-1%29%286%29)
= ![3 + 35(6)](https://tex.z-dn.net/?f=3%20%2B%2035%286%29)
= ![3 + 210](https://tex.z-dn.net/?f=3%20%2B%20210)
= ![213](https://tex.z-dn.net/?f=213)
Therefore : the 36th term = 213
