Q. Find the missing number so that the equation has infinitely many solutions.____x−13=−4x−13
Identify Condition: Identify the condition for infinitely many solutions.For an equation to have infinitely many solutions, both sides of the equation must be identical. This means that the coefficients of the variable x and the constant terms must be the same on both sides of the equation.
Set Up Equation: Set up the equation with the missing number.The given equation is ____x - 13 = -4x - 13. To have infinitely many solutions, the coefficient of x on the left side must be the same as the coefficient of x on the right side, which is −4.
Determine Missing Number: Determine the missing number. Since the coefficients must be the same for the equation to have infinitely many solutions, the missing number is −4.
