x > 4x>4

Explanation:

Solving inequalities is similar to solving equations.

First, we want to add color(blue)77 to both sides of the inequality:
3x - 7 quadcolor(blue)(+quad7) > 5 quadcolor(blue)(+quad7)

3x > 12

Now divide both sides by color(blue)3:
(3x)/color(blue)3 > 12/color(blue)3

So the answer is:
x > 4

This is the same thing as "x is greater than 4".

Hope this helps!

The answer is:
x > 4

Explanation:

3x - 7 > 5

Let's make it look simpler by isolating the x-base value.

We can add 7 on both sides to eliminate 7 on LHS

3x - 7 + 7 > 5 + 7
or, 3x > 12

Dividing both side by 3:

or, (3x)/3 > 12/3
or, x > 4
