Sure! Here are the completed solutions to the questions:
Question 1:
- The equation: \(-3x - 9 = -21\)
- Solve:
- \(-3x = -21 + 9\)
- \(-3x = -12\) (Add 9 to both sides)
- \(x = \frac{-12}{-3}\)
- \(x = 4\) (Divide both sides by -3)
Question 2:
- The equation: \(10x + 13 = -12\)
- Solve:
- \(10x = -12 - 13\)
- \(10x = -25\) (Subtract 13 from both sides)
- \(x = \frac{-25}{10}\)
- \(x = -2.5\) (Divide both sides by 10)
Question 3:
- Solve the equation \(5 - 6x = -7\):
- \(-6x = -7 - 5 \)
- \(-6x = -12\)
- \(x = \frac{-12}{-6}\)
- \(x = 2\)
Question 4:
- The equation: \(\frac{5}{3}x + \frac{11}{3} = -\frac{4}{3}\)
- Solve:
- \(\frac{5}{3}x = -\frac{4}{3} - \frac{11}{3}\)
- \(\frac{5}{3}x = -\frac{15}{3}\) (Subtract \(\frac{11}{3}\) from both sides)
- \(x = -\frac{15}{3} \times \frac{3}{5}\)
- \(x = -3\) (Multiply both sides by \(\frac{3}{5}\))
Question 5:
- The equation: \(0.24x - 0.74 = -1.1\)
- Solve:
- \(0.24x = -1.1 + 0.74\)
- \(0.24x = -0.36\) (Add \(0.74\) to both sides)
- \(x = \frac{-0.36}{0.24}\)
- \(x = -1.5\) (Divide both sides by \(0.24\))
