Q. Which equation has the solution x=5 x=5 ?\newline4x−4=−16 4 x-4=-16 \newline6x−1=77 6 x-1=77 \newline2x+4=14 2 x+4=14 \newline5x+8=41 5 x+8=41
  1. Check First Equation: We need to find which equation has x=5x=5 as its solution. To do this, we will substitute x=5x=5 into each equation and see which one holds true.\newlineLet's start with the first equation: 4x−4=−164x-4=-16.\newlineSubstitute x=5x=5 into the equation: 4(5)−4=−164(5)-4=-16.\newlineCalculate: 20−4=−1620-4=-16.\newlineCheck if the statement is true: 16=−1616=-16. This is not true.
  2. Check Second Equation: Now let's try the second equation: 6x−1=776x-1=77. Substitute x=5x=5 into the equation: 6(5)−1=776(5)-1=77. Calculate: 30−1=7730-1=77. Check if the statement is true: 29=7729=77. This is not true.
  3. Check Third Equation: Next, we'll test the third equation: 2x+4=142x+4=14. Substitute x=5x=5 into the equation: 2(5)+4=142(5)+4=14. Calculate: 10+4=1410+4=14. Check if the statement is true: 14=1414=14. This is true.
  4. Check Last Equation: Even though we have found the correct equation, we should check the last equation for completeness: 5x+8=415x+8=41. Substitute x=5x=5 into the equation: 5(5)+8=415(5)+8=41. Calculate: 25+8=4125+8=41. Check if the statement is true: 33=4133=41. This is not true.
