Q. Find the missing number so that the equation has infinitely many solutions.3x+1=x+1
Identify Equation: When an equation has infinitely many solutions, it means that both sides of the equation are identical. To find the missing number that makes the equation have infinitely many solutions, we need to make the coefficients of x on both sides of the equation the same.
Ensure Same Constants: The equation is 3x + 1 = ____x + 1. Since the constants on both sides are already the same (both are +1), we only need to ensure that the coefficients of x are the same on both sides for the equation to have infinitely many solutions.
Check Coefficients of x: The coefficient of x on the left side of the equation is 3. To have infinitely many solutions, the coefficient of x on the right side must also be 3.
Determine Missing Number: Therefore, the missing number that makes the equation have infinitely many solutions is 3. The equation becomes 3x+1=3x+1, which is true for all values of x.
