First distribute the 3 so you'll have:
12+12x=12x+12
Next you subtract 12 from both sides and you'll get:
12x=12x
then you divide both sides by 12 and you get:
x=x
Answer:

Step-by-step explanation:
1 1 1*1 1
---- * ----------- = ------- = ----------
2 9 2*9 18
We multiply the numerators together.
Then we multiply the denominators
Then we make a fraction
Answer:
-740
Step-by-step explanation:
18-72 equals -74
now -74 *10 equals-740
Out of every two consecutive numbers one will always be even. There is only one even prime number. Whether there are an infinite number of pairs of primes which differ by two (the twin prime conjecture) is still open e.g. 3 , 5; 41 , 43 ; 101 , 103 .
Answer:
19a+27b-54
Step-by-step explanation:
First distribute 7 into the first equation. (4a+3b-6) Multiply each coefficient and the constant by 7.
28a+21b-42
Then do the same for -3 and (3a-2b+4).
-9a+6b-12
Rewrite the equation 28a+21b-42-9a+6b-12.
Combine like terms: 19a+27b-54
