Q. Find the missing number so that the equation has infinitely many solutions. −3x−10=−3x+
Infinitely many solutions: When does this equation have infinitely many solutions? Infinitely many solutions occur when the both sides of the equation are identical.
Identical sides: -3x - 10 = -3x + ____To have infinitely many solutions, the constants on both sides must also be the same.
Matching constants: The constant on the left side is −10. For the equation to have infinitely many solutions, the constant on the right side must also be −10.
Determining missing number: Therefore, the missing number in the equation is −10. −3x−10=−3x−10
