Let's simplify the inequality:

7-2/3x<x-8

first we add 8 to each side:
15-2/3x<x

Now we add 2/3x to each side:
15<1 2/3x or 15<5/3x

Divide each side by 5/3 so the right side becomes x
9<x

Now you flip it:
x>9

therefore the answer is 1.

Hope this helps :)

The rules are similar to those for equations
first add 2/3 x to both sides
7 < x + 2/3 x - 8
add 8 to both sides
15 < 5/3 x
inverting we get
5/3 x > 15
now divide both sides by 5/3
x > 15 / 5/3 = 15 * 3/5 = 9

x > 9

What is the solution to this system of equations?

Maurinko [17]

Answer:

(x, y) = (5, -2)

Step-by-step explanation:

A graphing calculator provides a quick and easy way to find the solution.

_____

There are several other ways to solve these equations. Or you can estimate where the answer might be using logic like this:

The intercepts of the first equation are ...

x-intercept = 26/4 = 6 1/2
y-intercept = -26/3 = -8 2/3

So the graph of it will form a triangle with the axes in the 4th quadrant.

The intercepts of the second equation are ...

x-intercept = 11/3 = 3 2/3
y-intercept = 11/2 = 5 1/2

So the graph of it will form a triangle with the axes in the 1st quadrant. The x-intercept of this one is less than the x-intercept of the first equation, so the two lines must cross in the 4th quadrant.

The only 4th-quadrant answer choice is (5, -2).
