Answer:
x = - 3
Step-by-step explanation:
Given
12x + 7x = 5x - 42, that is
19x = 5x - 42 ( subtract 5x from both sides )
14x = - 42 ( divide both sides by 14 )
x = - 3

15.16 is like 379/25
Therefore, when u divide it u will get 15then 4/25
hope u got it :)
The answer is C because if you multiple both sides by 8 you get the equation of 6x = 320
