The solution set for all real numbers x such that 2x + 3 < 19 and 2x − 3 ≤ -7 is (, ]. note: if needed, type “-infinity” for -∞ and “infinity” for ∞.

Solve each inequality separately:

1.

Subtract 3 from both sides of the inequality

Divide the inequality by 2

2.

Add 3 to both sides of the inequality

Divide the inequality by 2

3. The solution set for the system of two inequalities is

or in other words

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
