Solve for x 4<2x+2<12

$4 < 2 x + 2 < 12$

Step 1

Move all terms not containing $x$ from the center section of the inequality.

Subtract $2$ from each section of the inequality because it does not contain the variable we are trying to solve for.

$4 - 2 < 2 x < 12 - 2$

Subtract $2$ from $4$ .

$2 < 2 x < 12 - 2$

Subtract $2$ from $12$ .

$2 < 2 x < 10$

Step 2

Divide each term in the inequality by $2$ .

$\frac{2}{2} < \frac{2 x}{2} < \frac{10}{2}$

Step 3

Divide $2$ by $2$ .

$1 < \frac{2 x}{2} < \frac{10}{2}$

Step 4

Cancel the common factor of $2$ .

Cancel the common factor.

$1 < \frac{2 x}{2} < \frac{10}{2}$

Divide $x$ by $1$ .

$1 < x < \frac{10}{2}$

Step 5

Divide $10$ by $2$ .

$1 < x < 5$

Step 6

The result can be shown in multiple forms.

Inequality Form:

$1 < x < 5$

Interval Notation:

$(1, 5)$
