Of the following options, what could be a possible first step in solving the equation -7x -5= x + 3
2 answers:
Answer:
Option a) Adding 7x to both the sides
Step-by-step explanation:
Given is an equation linear in one variable x.
To solve this equation we have to bring x terms on one side and constants on the other side.
Subtracting 5 from both sides will not eliminate the constant -5 hence wrong.
Adding x to both sides will make right side as 2x instead of eliminating x.
Combining like terms will give -7x-x not -7x+x hence incorrect
Adding 7x to both sides gets rid of x term on the left.
Hence this option is right answer

Step-by-step explanation:
Given -
In a recent survey, 18 people preferred milk, 29 people preferred coffee, and 13 people preferred juice as their primary drink for breakfast .
Total no of people is = 18 + 29 + 13 = 60
If a person is selected at random ,
The probability of person preferred milk =
The probability of person preferred coffee =
The probability of person preferred juice =
Probability that the person preferred milk as his or her primary drink =
P ( milk ) =
= = 0.3
