Question

What is the answer to this?

Answer 1

We must solve for x by simplifying both sides of the equation, then isolating the variable: 

1/2(x - 2) ≤ 1
1/2x - 1 ≤ 1
1/2x - 1 + 1 ≤ 1 + 1
1/2x / 1/2 ≤ 2 / 1/2
x ≤ 4

To prove this, enter 4 or any number smaller than 5 into the equation and solve to see if the statement still stands true.
