Question
Find the missing number so that the equation has infinitely many solutions.5x+=5x–13Submit
Solution
To make the equation have infinitely many solutions, both sides of the equation must be identical. This means that the number added to 5x on the left side of the equation must be the same as the number subtracted from 5x on the right side of the equation.
The equation is: 5x + _ = 5x - 13
Since we want both sides to be equal, the missing number should be -13.
So, the equation becomes: 5x - 13 = 5x - 13
Now, the equation has infinitely many solutions because for any value of x, both sides of the equation will always be equal.
