Which equation has the solution x=5 ? 4x-4=-16 6x-1=77 2x+4=14 5x+8=41

Check First Equation: We need to find which equation has x=5 as its solution. To do this, we will substitute x=5 into each equation and see which one holds true. Let's start with the first equation: 4x-4=-16. Substitute x=5 into the equation: 4(5)-4=-16. Calculate: 20-4=-16. Check if the statement is true: 16=-16. This is not true.Check Second Equation: Now let's try the second equation: 6x-1=77. Substitute x=5 into the equation: 6(5)-1=77. Calculate: 30-1=77. Check if the statement is true: 29=77. This is not true.Check Third Equation: Next, we'll test the third equation: 2x+4=14. Substitute x=5 into the equation: 2(5)+4=14. Calculate: 10+4=14. Check if the statement is true: 14=14. This is true.Check Last Equation: Even though we have found the correct equation, we should check the last equation for completeness: 5x+8=41. Substitute x=5 into the equation: 5(5)+8=41. Calculate: 25+8=41. Check if the statement is true: 33=41. This is not true.
