What value of x makes this equation true?

Pl help fast thank you

D. 27

Step-by-step explanation:

If you plug in the variable and solve it is equal on both sides. EX.

1. 27/3 -3 = 27/9 +3

2. 9-3 = 3+3

3. 6 = 6

X = 27

you multiply both sides and get 3x-27=x+27

then you move the terms and you get 3x-x=27+27 then calculate and get 2x=54 then divide and you get x==27

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
