Question

Solve for x. 9 ≤ 17 − 4x

Answer 1

If you would like to solve 9 <= 17 - 4x for x, you can do this using the following steps:

9 <= 17 - 4x
4x <= 17 - 9
4x <= 8      /4
x <= 8/4
x <= 2

The correct result would be x <= 2.

Answer 2

$\sf 9 \leq 17-4x\\Add\ 4x\ to\ both\ sides.\\4x+9 \leq 17\\Subtract\ 9\ from\ both\ sides.\\4x \leq 8\\Divide\ by\ 2\ on\ both\ sides.\\x \leq 2\\\\\\{\boxed{x \leq 2}$
