Q. Find the missing number so that the equation has no solutions. 2x−17=____x−1
Coefficients must match: To have no solutions, the coefficients of x must be the same on both sides of the equation, but the constants must be different.
Ensure equal coefficients: The coefficient of x on the left side of the equation is 2. To have no solutions, the missing coefficient of x on the right side must also be 2.
Compare constants: Now we compare the constants on both sides. On the left side, the constant is −17, and on the right side, it is −1. Since these constants are already different, we have ensured that the equation will have no solutions.
Find missing number: Therefore, the missing number that makes the coefficient of x on the right side equal to 2 is 2.
