Answer:
x≤-3 1/2 or x>1
Step-by-step explanation:
The way we solve this is we simply rearrange the equation using algebra.
Step 1) For the first inequality, subtract 1/2 from both sides. This gets x by itself and turns the RHS into -3 1/2.
Step 2) For the second, add 3 to both sides. Once again, x is by itself, and the RHS is equal to 1.

First set up the equation based on the description.

x + 16 = 3x
Use subtraction to get the "x"s on one side of the equation. You can next subtract <span>

x from both sides.
16 = </span>

<span> x
Now you can multiply both sides of the equation by </span>

<span> to solve for x
x = 6</span>
