Q. Find the missing number so that the equation has infinitely many solutions.−3x−16=x−16
Identify Equation Pattern: 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.
Check Constant Terms: Looking at the equation -3x - 16 = ____x - 16, we can see that the constant terms on both sides are already the same (−16). Therefore, we only need to match the coefficients of x.
Match Coefficients: To have infinitely many solutions, the coefficient of x on the left side (−3) must be the same as the coefficient of x on the right side. Therefore, the missing number is −3.
