To find the solution set of the inequality 2x > -8, we need to solve for x.
Divide both sides of the inequality by 2:
(2x)/2 > (-8)/2
x > -4
The solution set for this inequality is x > -4.
To find the solution set of the equation -5x + 7 = 12, we need to solve for x.
Subtract 7 from both sides of the equation:
-5x + 7 - 7 = 12 - 7
-5x = 5
Divide both sides of the equation by -5:
(-5x)/(-5) = 5/(-5)
x = -1
The solution set for this equation is x = -1.
Therefore, the solution set for the system of equations 2x > -8 and -5x + 7 = 12 is x > -4 and x = -1.
