Q. Find the missing number so that the equation has no solutions.____x−10=−5x+7
Identify Situation: To determine the missing number that would result in no solutions, we need to create a situation where the equation is never true, regardless of the value of x. This occurs when the coefficients of x are the same on both sides of the equation, but the constants are different.
Write Equation: Let's write down the equation with the missing number represented by a blank: _____x−10=−5x+7. To have no solutions, the coefficient of x on the left side must be the same as the coefficient on the right side, which is −5. Therefore, the missing number is −5.
Determine Missing Number: However, for the equation to have no solutions, the constants on both sides must be different. In this case, the constants are already different (−10 on the left and +7 on the right). So, by having the same coefficients and different constants, the equation will have no solutions.
