Question

X - 3 greater than 7

Answer 1

X -  3 > 7
x > 7 + 3
x > 10

answer x > 10

Answer 2

First, let's work on the left hand side of your inequality, the x-3
This means, for instance, to see if it can be simplified at all.
x-3 evaluates to x-3So, all-in-all, the left hand side of your inequality can be written as: x-3Now, let's work on the right hand side of your inequality, the 7
The right hand side of your inequality can be written as: 7So with these (any) simplifications, the inequality we'll set out to solve is:
x-3  7
Move the -3 to the right hand side by adding 3 to both sides, like this:
To the left hand side:
-3 + 3 = 0The answer is xTo the right hand side:
7 + 3 = 10
Now, the inequality reads:
x>=10 
To isolate the x, we have to divide both sides of the inequality by the other "stuff" (variables or coefficients)
around the x on the left side of the inequality.
and this is the final solution to your inequality.

The answer is 10
