The correct Answer is:
To solve the inequalities given in the problem step by step, we will break down each part of the question. ### Step 1: Solve the first inequality We start with the first inequality: \[ 4(2x + 3) > 5 - x \] 1. Distribute the 4: \[ 8x + 12 > 5 - x \] 2. Add \( x \) to both sides: \[ 8x + x + 12 > 5 \] \[ 9x + 12 > 5 \] 3. Subtract 12 from both sides: \[ 9x > 5 - 12 \] \[ 9x > -7 \] 4. Divide both sides by 9: \[ x > -\frac{7}{9} \] \[ x > -0.777... \] (approximately -0.7) ### Step 2: Solve the second inequality Now we move on to the second inequality: \[ 5x - 3(2x - 7) > 3x - 1 \] 1. Distribute the -3: \[ 5x - 6x + 21 > 3x - 1 \] 2. Combine like terms on the left side: \[ -x + 21 > 3x - 1 \] 3. Add \( x \) to both sides: \[ 21 > 4x - 1 \] 4. Add 1 to both sides: \[ 22 > 4x \] 5. Divide both sides by 4: \[ \frac{22}{4} > x \] \[ 5.5 > x \] \[ x < 5.5 \] ### Step 3: Combine the results From the two inequalities we have: 1. \( x > -\frac{7}{9} \) (approximately -0.7) 2. \( x < 5.5 \) ### Step 4: Determine the range of x The solution can be summarized as: \[ -\frac{7}{9} < x < 5.5 \] ### Step 5: Identify possible values of x Now we need to check which values of \( x \) satisfy this range. The values must be greater than approximately -0.7 and less than 5.5.
