To find the solution set of 2x - 3 = 5, we can start by adding 3 to both sides of the equation:
2x - 3 + 3 = 5 + 3
This simplifies to:
2x = 8
Next, we can divide both sides of the equation by 2 to solve for x:
2x/2 = 8/2
This simplifies to:
x = 4
So, the solution to the equation 2x - 3 = 5 is x = 4.
To find the solution set of 5x + 3 > -12, we can start by subtracting 3 from both sides of the inequality:
5x + 3 - 3 > -12 - 3
This simplifies to:
5x > -15
Next, we can divide both sides of the inequality by 5 to solve for x. But since we are dividing by a positive number, the inequality symbol remains the same:
5x/5 > -15/5
This simplifies to:
x > -3
So, the solution to the inequality 5x + 3 > -12 is x > -3.
Therefore, the solution set to the system of equations is x = 4 and x > -3.
