Alright, so to understand algebra
use PEMDAS
parenthasees
exponents (square roots count as exponents)
multiply or divide
add or subtract
basically try to isolate the unknown/vareable/xterm
so
3(2x-1)-10=8+5x (assuming you meant to type 8+5x and not 8=5x)
first distribute using distributive property
a(b+c)=ab+ac
3(2x-1)=3 times 2x+3 times -1=6x-3
6x-3-10=8+5x
add like terms
6x-13=8+5x
subtract 5x from both sides
x-13=8
add 13 to both sdies
x=21
Answer:
11 is the common difference of the given sequence.
Step-by-step explanation:
Here the given sequence is
Terms 1 2 3 4
Sequence -12 -1 10 21
Now we know the arithmetic sequence is -12, -1, 10, 21.........n terms
common difference of an arithmetic sequence is represented as difference of nth term and (n-1)th term.
Therefore common difference d = -1 - (-12) = -1 +12 = 11
common difference 11 is the right answer.
