To solve 2x > -8, we divide both sides of the inequality by 2: x > -4.
To solve -5x + 7 = 12, we subtract 7 from both sides of the equation: -5x = 5
Finally, we divide both sides by -5 to solve for x: x = -1.
Therefore, the solution set is -4 < x < -1.
Determine the solution set of 2x>−8 and −5x+7=12.
