Solve the System of Inequalities t+14>=15 or t-9<-10

$t + 14 \geq 15$ or $t - 9 < - 10$

Move all terms not containing $t$ to the right side of the inequality.

Subtract $14$ from both sides of the inequality.

$t \geq 15 - 14$ or $t - 9 < - 10$

Subtract $14$ from $15$ .

$t \geq 1$ or $t - 9 < - 10$

Move all terms not containing $t$ to the right side of the inequality.

Add $9$ to both sides of the inequality.

$t \geq 1$ or $t < - 10 + 9$

Add $- 10$ and $9$ .

$t \geq 1$ or $t < - 1$

The union consists of all of the elements that are contained in each interval.

$t < - 1$ or $t \geq 1$

The result can be shown in multiple forms.

Inequality Form:

$t < - 1 or t \geq 1$

Interval Notation:

$(- \infty, - 1) \cup [1, \infty)$
