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

Answer:
(0, -4)
Step-by-step explanation:
The coordinates of the points from which the directed line segment extends = (-6, -6) to (9, -1)
The ratio the required point partitions the line = 2 to 3
The formula for finding the coordinate of a point that partitions a line AB into a ratio 'a' to 'b', where the coordinates of, A = (x₁, y₁) and B = (x₂, y₂) is given as follows;
Therefore, the required point is located as follows;
The coordinates of the point is (0, -4)
