Math Problem Statement

Match each equation on the left to its solution on the right. Some answer choices on the right will be used more than once.

Solution

Let's go through each equation from the image and solve it step-by-step to match it with the correct solution.

  1. Equation: 4+x=8x54 + x = -8x - 5

    • Combine like terms: x+8x=54x + 8x = -5 - 4 9x=99x = -9 x=1x = -1
    • Solution: x=1x = -1
  2. Equation: 2(5x+2)=10x42(5x + 2) = 10x - 4

    • Expand both sides: 10x+4=10x410x + 4 = 10x - 4
    • Subtract 10x10x from both sides: 4=44 = -4
    • This is a contradiction, so there is no solution.
  3. Equation: 7+2x=2x77 + 2x = 2x - 7

    • Subtract 2x2x from both sides: 7=77 = -7
    • This is also a contradiction, so there is no solution.
  4. Equation: 3x+3=3(1x)-3x + 3 = 3(1 - x)

    • Expand the right-hand side: 3x+3=33x-3x + 3 = 3 - 3x
    • Add 3x3x to both sides: 3=33 = 3
    • This is always true, meaning the solution is x=x = all real numbers.

Final Matching:

  1. 4+x=8x54 + x = -8x - 5x=1x = -1
  2. 2(5x+2)=10x42(5x + 2) = 10x - 4No solution
  3. 7+2x=2x77 + 2x = 2x - 7No solution
  4. 3x+3=3(1x)-3x + 3 = 3(1 - x)x=x = all real numbers

  1. How do you determine when an equation has no solution?
  2. Can an equation have more than one solution?
  3. What does it mean for an equation to have "all real numbers" as a solution?
  4. How would you solve more complex multi-variable equations?
  5. What are the different types of contradictions in equations?

Tip: Always check your final solution by substituting it back into the original equation to verify correctness.
