Solve for x. 6x-10≤8 or 1/3 x+6>12

Feliz [49]

The solution is

$x\le 3 \:or \:x>18$

$EXPLANATION$

$6x-10\le 8\: or \frac{1}{3}x+6>12$

We group like terms, to obtain;

$6x\le 8+10\: or \frac{1}{3}x>12-6$

Simplify to get,

$6x\le 18\: or \frac{1}{3}x>6$

We further simplify to get;

$x\le 3\: or x>18$

This can also be rewritten as;

$x\le 3, x>18$

$(-\infty 3] \cup (18,+ \infty)$

This can be represented on the number line as shown in the diagram.
