Writing and solving an equation of ratios is the way to go here. See if you can figure out why the following is correct:
x+3 x
----- = -------
12 x+3
Then (x+3)^2 = 12x, and x^2 + 6x + 9 = 12x, so that x^2 - 6x + 9 = 0
This is the square of (x - 3). Thus, x-3 = 0, and x = 3.
The value of x is 3.
Answer:
x > 3
Step-by-step explanation:
The inequality to solve is:
5 - 4x < - 7
We will solve this using same method as solving an equation. We will take numbers to one side and variables to another and multiply and divide accordingly.
So,
That means "x is greater than 3", so we can write:
x > 3
Answer:
110
Step-by-step explanation:
