What is the solution set of 2x−3=5 and 5x+3>−12 ?(1 point)

1 answer

To find the solution set for the equations \( 2x - 3 = 5 \) and \( 5x + 3 > -12 \), we will solve each inequality separately.

  1. Solve the equation \( 2x - 3 = 5 \): \[ 2x - 3 = 5 \] Add 3 to both sides: \[ 2x = 8 \] Divide by 2: \[ x = 4 \]

  2. Solve the inequality \( 5x + 3 > -12 \): \[ 5x + 3 > -12 \] Subtract 3 from both sides: \[ 5x > -15 \] Divide by 5: \[ x > -3 \]

  3. Combine the results: The solution to \( 2x - 3 = 5 \) gives us \( x = 4 \), and the solution to \( 5x + 3 > -12 \) gives us \( x > -3 \).

  4. Determine the overall solution set: Since \( 4 > -3 \), the solution set for both conditions is \( x \) must be both \( 4 \) (from the equality) and greater than \(-3\) (from the inequality). Since the equality provides a specific value, the solution set is \( x = 4 \).

Thus, the solution set is: \[ { x = 4 } \]
