Q. Find the missing number so that the equation has infinitely many solutions.−5x−14=x−14
Identify Solutions: Identify when the equation has infinitely many solutions. An equation has infinitely many solutions when both sides of the equation are identical. This means that the coefficients of x and the constants on both sides must be the same.
Compare Coefficients: Compare the coefficients of x on both sides of the equation.The left side of the equation has a coefficient of −5 for x. For the equation to have infinitely many solutions, the missing coefficient on the right side must also be −5.
Verify Constants: Verify that the constants on both sides of the equation are the same.The constants on both sides of the equation are −14. Since they are already the same, we do not need to change anything about the constants.
Conclude Missing Number: Conclude the missing number.The missing number is the coefficient of x on the right side of the equation that makes it identical to the left side. Therefore, the missing number is −5.
